Speedmaster Chronoscope 43 mm
329.92.43.51.10.001
This 43 mm model has been crafted in exclusive OMEGA bronze gold, with an oxidized bronze dial featuring a special patina and opaline finish. Its polished brown ceramic bezel and vintage enamel tachymeter scale, leaf hands and Arabic numerals are also PVD-coated in 18K bronze gold. A unique "spiral" circuit motif runs beneath the minutes.
Its distinctive feature is a dial with three distinct measuring scales printed on it in the spiral style of the 1940s: a tachometric scale, a pulsometer and a telemetric scale.
Offered with a brown leather strap, it also features a silvered small seconds counter at 9 o'clock and a silvered 60-minute and 12-hour totalizer at 3 o'clock. The watch is powered by the hand-wound OMEGA Co-Axial Master Chronometer 9908 caliber.
