Watches and Wonders 2023

Watches and Wonders 2023 ran from 27 March to 2 April. It was the sixtieth year of the Cosmograph Daytona and the seventieth of the Explorer, and those two birthdays sat in the same week. That is a useful way to date the catalogue. It is a poor way to describe what Rolex, Tudor, and Cartier actually put out.

Rolex did not treat the week as a single anniversary with a few extras. The steel Cosmograph Daytona arrived with a new calibre and a closed back. A gold dress watch arrived with a sapphire back. A titanium Yacht-Master arrived at 42 mm. The Explorer moved to 40 mm while a 36 mm watch already existed. A yellow Rolesor GMT-Master II took a grey-and-black Cerachrom bezel. The Sky-Dweller changed calibre and found new metal and dial combinations. Tudor spent the same week on a METAS Black Bay, a 37 mm Black Bay 54, and a paler GMT. Cartier spent it on openwork and lacquer inside the Santos family.

Heat is not a footnote if the strap is leather. On a cuff the week ran from a 40 mm Daytona to a 42 mm titanium Yacht-Master, a 40 mm Explorer, a 39 mm gold 1908, a 37 mm Black Bay 54, and a square Santos. Those sizes are the argument. The rest is whether a closed steel chronograph, a gold watch you can see through, a titanium sports watch, or a smaller Tudor is the object that actually belongs on the wrist that will wear it.

Cosmograph Daytona

The steel watch is the 126500LN. Forty millimetres across, 11.9 mm thick, 47.6 mm lug to lug, a black Cerachrom tachymeter, 100 metres, a solid back. Calibre 4131. Seventy-two hours. About SAR 133,851 on 18 August 2026. Across the family, the same calibre. The anniversary did not produce a new shape so much as a new engine behind a familiar one.

Forty millimetres is the Daytona’s present tense. On a cuff it is not a shy watch. The thickness is honest. The lug span is the figure that decides whether the case sits inside a shirt or argues with it. Rolex did not publish a thinner steel chronograph for the occasion. It published a steel chronograph with a longer reserve, a ceramic bezel that will not scar the way an aluminium insert will, and a back you cannot look through.

A platinum Daytona, the 126506, opened that back so the movement could be seen. The steel one did not. That is not an unfinished thought. It is how Rolex ranks the two watches. The expensive metal is allowed to show the work. The steel watch, the one that will carry the sixtieth year in conversation, keeps the work private. Anyone who wanted the anniversary to be a display of finishing will have to look at platinum, or look elsewhere in the same week.

Calibre 4131 is the sentence the whole family now shares. Seventy-two hours is long enough that a watch left from Thursday evening to Sunday morning is still running. One hundred metres is the usual Rolex promise for a sports chronograph, which is more swimming than diving, and more than a dress watch will offer. The solid back on steel is the detail that will irritate collectors who like to see a movement and will not trouble anyone who wanted a Daytona that looks like a Daytona.

Was the week only this anniversary? Only if you stop reading. The Daytona is the headline because sixty years is a round number and because this is still the watch people mean when they mean Rolex in a hurry. The catalogue around it was doing other work. For the wider house, the Rolex collection after that week is not a shrine to one chronograph. If the question is which current Rolex to live with, the longer route is the best Rolex watches guide rather than a single reference.

1908

The gold 1908 arrived as a new dress watch. Thirty-nine millimetres. 9.5 mm thick. Fifty metres. Calibre 7140. Sixty-six hours. A sapphire back. Yellow gold 52508 or white gold 52509. Intense white or black dial, small seconds at six, Arabic 3, 9 and 12. Alligator strap, Dualclasp. Leather is a choice.

Thirty-nine millimetres and 9.5 mm is a different cuff from the Daytona. The 1908 occupies less height. It will slide under a cuff where 11.9 mm of steel chronograph will not. That is the practical reason to look at it in the same week as the 126500LN. The poetic reason is the open back. After a steel Daytona that refuses to show calibre 4131, Rolex offered a gold watch that shows calibre 7140 as a matter of course.

The dial language is spare: intense white or black, small seconds at six, Arabic numerals only where they earn their place. It is a dress watch with a sports-watch house behind it, which is why the 50 metres and the 66-hour reserve matter more than they would on a watch that expected to live in a drawer. Dualclasp on alligator is a serious clasp on a serious strap. It is also a leather strap.

Heat matters if the strap is leather. Alligator in sustained heat is not a theoretical problem. It is sweat, salt, and a material that does not forgive neglect. A gold dress watch on a Dualclasp alligator strap is beautiful in the catalogue. In a climate where the air itself is work, leather is a commitment. The 1908 of that week is on alligator, not an Oyster bracelet. Anyone who wants the watch has to want the strap, or be prepared to change it, or be prepared to treat leather as a seasonal object. That is not a defect in the 1908. It is the condition of wearing it.

A closed steel Daytona, or a 1908 you can see through? The week posed that question without answering it. They are not substitutes. One is a 40 mm chronograph with a ceramic tachymeter and a solid back. The other is a 39 mm gold watch with small seconds and a sapphire back. The tension is taste, metal, and whether you want the movement as a private fact or as a view.

Sky-Dweller

The Sky-Dweller that week ran on calibre 9002. That is the mechanical news. The rest is colour and metal, which is how Rolex talks when it does not want to talk about architecture. First white-gold Sky-Dweller on a black Oysterflex. Mint-green dial on white Rolesor. Blue-green dial on Everose gold.

A white-gold Sky-Dweller on black Oysterflex is a dress-adjacent sports watch that has decided the bracelet is optional. Oysterflex is elastomer with a metal core, which is a different proposition from alligator in heat. It will not drink sweat the way leather will. It will not look like a gold dress watch either. The mint-green dial on white Rolesor is the louder object: steel and white gold, a colour that will not hide. The blue-green Everose watch is warmer metal under a cooler dial. Three ways to own the same complication, none of them a Daytona, none of them a 1908.

The Sky-Dweller remains the Rolex that asks more of the wearer than a date just past the cyclops. Annual calendar, dual time, a Ring Command bezel that is a tool rather than a decoration. Calibre 9002 is the week’s update to that machine. The new combinations are how the house made sure the update would be seen on a wrist, not only in a specification line.

Yacht-Master 42

The Yacht-Master 42 in RLX titanium is the 226627. Forty-two millimetres. Titanium. Calibre 3235. Seventy hours. One hundred metres. About SAR 69,568 on 18 August 2026. Thickness unpublished.

Forty-two millimetres is the largest round sports watch in this week’s Rolex group. Titanium is the reason it can be that size without becoming a gold-and-steel statement. RLX titanium is Rolex’s own grade, lighter than steel, less ceremonial than platinum, and still a Yacht-Master rather than a tool watch from another house. The Yacht-Master line has always sat slightly to the side of the Submariner: a sports watch with a precious or unusual material, a raised bezel, a different idea of what a diver’s layout is for.

The unpublished thickness is a real gap. Catalogue readers who live by millimetres of height will have to wait for a figure Rolex did not give that week. What it did give is diameter, metal, movement, reserve, and depth. Calibre 3235 is the current automatic with a 70-hour reserve, which puts the titanium watch on the same endurance as the Explorer 40 and the yellow Rolesor GMT-Master II, and two hours short of the Daytona’s 4131.

On a cuff, 42 mm of titanium is a different physical fact from 40 mm of steel Daytona. Wider than the 40 mm steel watches, and aimed at someone who wanted the Yacht-Master without another gold watch. About SAR 69,568 is less than the steel Daytona’s SAR 133,851 and less than the yellow Rolesor GMT. It is not a cheap Rolex. It is the week’s argument that size and metal can move together.

Explorer 40

The Explorer 40 is the 224270. Forty millimetres. 11.6 mm thick. Calibre 3230. Seventy hours. One hundred metres. About SAR 42,819 on 18 August 2026. A 36 mm Explorer already existed.

Seventy years sat in the same week as the Daytona’s sixty, and Rolex answered the birthday with diameter. The 36 mm watch was not withdrawn. The 40 mm watch was added. That is a more interesting decision than a replacement would have been. The Explorer’s job has always been the simple Rolex: Mercedes hands, 3-6-9, a black dial, no date, no bezel theatre. At 40 mm it is still that watch. It is also a watch that shares a cuff language with the Daytona rather than with older, smaller Explorers.

11.6 mm against the Daytona’s 11.9 mm is close in height and distant in purpose. The Explorer has no tachymeter, no chronograph pushers, no ceramic insert. Calibre 3230 is the no-date automatic. Seventy hours. One hundred metres. About SAR 42,819, which is the lowest Rolex figure in this week’s set and still a Rolex figure. The Explorer collection after 2023 is a two-size story. Anyone who wanted the seventieth year to be a return to a smaller watch was looking at the watch that already existed.

Titanium at 42 mm, Explorer at 40 mm, or Tudor at 37 mm? The week left all three on the table. The Explorer 40 is the orthodox answer: steel, simple, the diameter Rolex now treats as standard for a sports watch. It is not the lightest, not the smallest, and not the one with a burgundy bezel. It is the one that looks like an Explorer.

GMT-Master II

The yellow Rolesor GMT-Master II with a grey-and-black Cerachrom bezel is the 126713GRNR. Forty millimetres. Calibre 3285. Seventy hours. About SAR 103,377 on 18 August 2026. Full yellow gold 126718GRNR is another watch. A steel grey-and-black GMT-Master II arrived the following year.

Grey-and-black on yellow Rolesor is a quieter bezel than the usual red-and-blue or black-and-blue combinations, set on louder metal. Steel and yellow gold, a Cerachrom insert that will not fade, a GMT hand for a second zone. Calibre 3285 is the current GMT automatic, independent local-hour jumping, 70 hours. Forty millimetres puts it on the same cuff as the Daytona and the Explorer 40, with a rotating bezel the Explorer does not have and a complication the Daytona does not have.

The full yellow gold 126718GRNR is the same bezel idea without the steel. It is a different watch, and it was already part of the conversation that week. The steel grey-and-black watch was not. That one arrived in 2024. Anyone who wanted this bezel on steel in March 2023 was early. What Rolex offered then was grey-and-black with gold in the case, either mixed or solid. The GMT-Master II line can absorb that kind of delay. The bezel colour was the news. The steel version was the sequel.

About SAR 103,377 sits between the titanium Yacht-Master and the steel Daytona. That is the Rolesor tax, and it is also the price of a GMT in the current catalogue. For a traveller who wanted yellow gold in the mix and a bezel that does not shout, this was the 2023 answer. For a traveller who wanted the same bezel without gold, the answer was the following year.

Tudor

Tudor’s week was not a supporting act. A Black Bay 41 arrived with a burgundy bezel and METAS-certified calibre MT5602-U. A 37 mm Black Bay 54 arrived with calibre MT5400, COSC, not METAS. A Black Bay GMT took a pale opaline dial. Three watches. Three different ideas of what a Black Bay is for.

The 41 mm burgundy watch is the one that will be discussed in certification circles. METAS is a harder room than COSC: magnetic resistance, positional testing, a reserve test that includes the watch in daily conditions. Calibre MT5602-U is Tudor saying the 41 mm Black Bay can live in that room. The burgundy bezel is the part you can see. The certification is the part you buy because you care about it, or you ignore because you wanted the colour.

The Black Bay 54 is the one that changes the cuff. Thirty-seven millimetres. 11.24 mm thick. 46 mm lug to lug. Two hundred metres. Calibre MT5400. Seventy hours. COSC, not METAS. It is smaller than the Rolex sports watches of the same week and deeper than any of them. Two hundred metres against Rolex’s 100 metres on the Daytona, the Yacht-Master 42, and the Explorer 40. Thickness close to the Explorer. Lug span shorter than the Daytona’s 47.6 mm. On a cuff it is the compact watch of the week, and it is still a Black Bay: snowflake hand, gilt accents, a diver’s bezel, a bracelet that knows it is a sports watch.

COSC and not METAS is a distinction, not a slight. The 54 shares a family face with the 41 and does not share the 41’s METAS certificate. Seventy hours matches the Rolex 3235 and 3230 watches. The 37 mm case is the point. Anyone who found 40 mm and 42 mm too much of a contemporary habit had a new Tudor to consider, from a house that has spent years making the Black Bay the watch you buy when the Rolex you wanted is either unavailable or larger than the wrist.

The pale opaline Black Bay GMT is the third object. A GMT with a quieter dial than the usual black-and-gilt Black Bay look. Opaline will pick up light rather than swallow it. It is not the 54, and it is not the burgundy 41. It is Tudor using the same week to soften a complicated watch without shrinking it. Together the three watches keep Tudor from being a footnote to Rolex’s anniversaries. The 54 is the one that belongs in the cuff list. The other two are why the house was busy.

Santos

Cartier’s week sat on a square. Santos-Dumont skeleton work with calibre 9629 MC, the rotor shaped as the Demoiselle. Santos de Cartier with graduated green or blue lacquer dials. One watch opened to the air. The other held colour in lacquer that changes as it moves from the centre to the edge.

The Santos-Dumont skeleton is jewellery and mechanics in the same case. Calibre 9629 MC is the movement. The Demoiselle rotor is the joke that is also the point: an early flying machine, turning, visible, a Cartier story rather than a Rolex one. Nobody needed this watch to dive, travel, or time a lap. It exists because a Santos can be a frame for openwork, and because Cartier still treats that frame as a design problem rather than a sports-watch problem.

The Santos de Cartier with graduated green or blue lacquer is the wearable half of the same thought. A square case, a bracelet that has always been part of the design, a dial that is not a flat colour. Green or blue, darker or denser as the eye moves. Lacquer is a finish that asks to be seen in light. It is also a finish that does not care about tachymeters. On a cuff a square watch occupies space differently from a 40 mm Oyster. The corners are the measurement. The bracelet is the rest of the architecture.

Cartier did not spend the week competing with a Daytona anniversary. It spent the week reminding anyone watching that the Santos is a family: open on one side, coloured on the other, square in both cases. In a week of Rolex diameters and a Tudor 37 mm, the square is the shape that does not enter the millimetre argument at all.
