About this reference
The Tudor Royal M28400-0006 brings a blue sunburst dial to the collection's 34 mm stainless-steel format. Roman markers sit within the clean round layout, edged by a fluted steel bezel and sapphire crystal, while the silver steel bracelet and folding clasp keep the watch's proportions balanced. A screw-down crown, Super-LumiNova and 100-metre water resistance add to its specification.
Inside, Tudor Calibre T601 provides the Royal's time-and-date display. This 5.5 mm-high, 25.6 mm-diameter T-series automatic movement uses a full rotor with bidirectional winding and stores 38 hours of power reserve. It runs at 28,800 vibrations per hour and includes a quickset date and stop-seconds mechanism. The Nivarox hairspring and 25 jewels are among the calibre's defining technical details, giving the blue 34 mm Royal a precise mechanical foundation.
