The replica Omega Speedmaster Chronoscope Co-Axial Master Chronometer chronograph dial is modeled after a multi-scale chronograph equipped with a cal 33.3 produced by Omega in the 1940s. More Omega Speedmaster clone watches.
The Chronoscope does a good job of reproducing the multi-scale design, with each of the three scales clearly arranged around the center. But unlike vintage watches where the scales are usually in different colors, the three scales on the Chronoscope dial are all in the same tone. Still, due to the size of the dial, they look easy to read because the font is large. The rest of the dial has attractive details, such as a fine concentric engraved seal ring, and the hour numerals echo the two-tone finish on the vintage dial. The sub-dials are also recessed, which also enhances the vintage-style look.
The replica Omega Speedmaster Chronoscope Co-Axial Master Chronometer chronograph is available in four versions, three in stainless steel and one in Omega’s exclusive bronze-gold. All are 43mm in diameter, a bit larger than the classic Speedmaster Moonwatch, but still acceptable given the triple indices on the dial. However, this size is also thinner than the 44.25mm Speedmaster Racing and Moonphase.
Also new is the hand wound Co-Axial Master Chronometer Calibre 9908 set behind the boxy sapphire crystal, beating at 4 Hz or 28,800 bph with 60 hours in its power reserve on a full wind. It is essentially an iteration of the 9900 minus a rotor and presenting a new ¾ plate. Twin barrels of 44 jewels – anti-wear diamond-like carbon coatings– ensure the column wheel runs with as little friction as possible and with utmost precision for the functions. A nice and new touch is the design of the bridge which features an Arabesque wave motif that flows out from the balance wheel at the lower side instead of dead centre.
