Series
The Speedmaster is a chronograph first: a crown with a pusher above and below it, a tachymeter scale on the bezel for converting elapsed time into a rate, and counters set into the main dial. Two very different executions of it sit in this collection. One is 44.25 mm and machined from black ceramic, so the case, bezel and dial are all the same dark material and the print has to do the work of separating them. The other is 42 mm in steel with a silver dial, a blue ceramic bezel and a medallion in one of the registers. Each page states which read sits where on its own dial.
In this collection
All-black Speedmaster in ceramic, 44.25 mm: two counters, a date above six o’clock, the tachymeter scale on the bezel and a black strap.
Silver dial with blue markers and three blue registers, a blue ceramic bezel, and the anniversary medallion in the nine o’clock subdial.
This collection lists a small number of configurations. Series not shown here can still be discussed — send the model and reference and availability is checked for you.
Design notes
On the black ceramic watch, case, bezel and dial are all dark, so legibility comes from the print and the applied indexes rather than from contrast between the case and the dial. On the silver-dial anniversary reference the opposite is true: the dial is the light element, the bezel is a band of blue ceramic, and the markers and hands carry blue against the pale surface. Those two approaches photograph very differently, which is why each page describes the frame it is based on instead of a general impression of the line.
The numbers around the bezel are not a second time display. They convert the time taken for one known unit of distance into an average speed: sixty seconds for one unit corresponds to sixty units an hour, thirty seconds to 120, and the spacing gets wider as the numbers climb. Reading it is independent of whether the chronograph itself starts, stops and resets cleanly, and both are worth checking separately on a video of the actual watch.
These notes describe the design as it appears in the photographs on this site. Movement, water resistance, weight and material composition are not stated here, because those belong to the specific unit being offered and are confirmed in the conversation before anything is paid.
