Speedmaster Chronoscope 43 mm
329.92.43.51.10.001
This 43 mm model is crafted in OMEGA’s exclusive Bronze Gold, with an oxidised bronze dial featuring a special patina and opaline finish. Along with a polished brown ceramic bezel ring with its tachymeter scale in "vintage" enamel, the leaf-shaped hands and Arabic numerals also feature an 18K Bronze Gold PVD coating. A unique “spiral” track pattern runs beneath the numbers.
Most notably, the dial is printed with three distinctive timing scales in a 1940’s “snail” design, including a tachymeter scale, a pulsometer scale and a telemeter scale.
Presented on a brown leather strap, the watch features a silvery small-seconds counter at 9H, and a silvery 60-minute and 12-hour recorder at 3H. Inside, the timepiece is driven by the manual-winding OMEGA Co-Axial Master Chronometer Calibre 9908.

Anti-magnetic : The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).

Chronometer : Label given to a watch which has been successfully tested by an accredited and independent laboratory in order to receive a certificate compliant with the chronometer ISO 3159 standard.
Master Chronometer Certified : Guaranteeing the Swiss industry’s highest standard of precision, performance and magnetic-resistance, as set by the Swiss Federal Institute of Metrology (METAS).
Pulsometer : A watch with a scale to measure the number of heartbeats per minute.
Small seconds : A hand on a sub-dial which tracks seconds typically it completes a full rotation in one minute.
Tachymeter : A tachymeter watch has a function for measuring speed. It is a chronograph with a graduated dial on which speed can be read in kilometres per hour based on a 1000 metre distance.
Telemeter : This precision tool can measure exactly how far you are from something that is visible and audible, such as your distance from a lightening storm.
Time zone function : Allows the hour hand to be easily adjusted to different time zones without stopping the watch.
Transparent caseback : A transparent caseback – frequently made of sapphire – makes it possible to see the movement inside the watch.
