About this reference
With its 39 mm stainless-steel case and fixed bezel, the Tudor 1926 M91550-0005 gives the collection a broad, composed canvas for a white opaline dial. The steel bracelet and applied markers preserve the watch's formal clarity, while sapphire crystal, a screw-down crown and 100-metre water resistance keep the specification grounded in daily practicality.
The reference uses the automatic T601 calibre, a bidirectionally wound movement that can also be wound by hand and provides a quickset date. It is 25.6 mm wide and 5.5 mm high, with 25 jewels, a Nivarox hairspring and Swiss-lever escapement. Operating at 28,800 vph and delivering 38 hours of reserve, it gives this white-dial 1926 a measured mechanical pulse.
