Since as early as 1885, the company had been turning out pocket chronographs, and their first wrist model from 1913 was just one of these huge pocket replica watches converted with the addition of thin metal wires soldered to the case to allow for a strap to be equipped.
The crown and single push button are made of Omega’s own 18k Sedna gold, their red alloy version of the valuable metal material. It implies the watch an inherent sense of aging, similar to real vintage pieces where the underlying brass has started to show through. 
Luckily, they haven’t tried to add any artificial patina as some other different brands do with their retro-reissues. The case and dial are left clean, just as they would have been way back when, but they have totally stayed accurate to the time period.
As a bi-register chronograph, it has two rather big sub-dials, what’s more, in the middle is a standard sweep seconds hand, again in Sedna gold.
Opening up the hinged ‘officer’ case back, you get to see to just what extent replica Omega has stayed faithful to its roots. Behind the sapphire crystal is one of the actual calibers used in the 1913 models hard at work.
It is said that the amazing Omega found 18 of these movements in their vaults; 18″‘ CHRO hand-wound mechanisms usually found in pocket watches, which explains why the pusher for the chronograph functions is on the bottom, underneath the six o’clock marker.
After several hundred hours of refurbishing work on each one, even using the real manufacturing machines, they emerged as the Caliber 3018. New parts had to be built particularly for each movement, as no two were an exact match—being made long before today’s level of consistency in precision engineering.
It might not be one of the fake Omega’s latest antimagnetic, hyper-accurate Master Co-Axial movements, but watching the 2.5Hz frequency caliber, with its horizontal clutch and balance wheel, breathe away inside that enormous case is a true taste of watch-making history.
All 18 are being presented in a very nice handcrafted leather trunk, as well as two extra straps, one in burgundy, the other in novonappa leather. Besides that, the lucky owners will receive a special tool to change the straps together with a spring bar container, loupe, and travel pouch. 
However, there’s no getting away from the fact that it is an important chunk of change. But for those who don’t have enough money for it, and who have a hankering for the real good old days when watch-making was still in its infancy, the First Omega Wrist Chronograph replica watch is a little short of a masterpiece.
