The late 1930s saw a mini revolution for Omega - the introduction of the Omega 23.4SC calibre. This was their first production Omega watch with a central sweep seconds hand, a progression from the seconds being within a small sub-dial at 6. It was marketed in the guise of two main designs. The Omega Medicus was the obvious application for the medical profession as the seconds were so much easier to read when counting a patients pulse. Then there was the Omega Naiad, the watch for sale here. Not only did it boast the new sweep seconds hand but it was the first production Omega to be water resistant. Most of the Naiads were characterised by a slightly oversized case-back compared to the case when measured by diameter, producing a small step. Note that this watch is no longer water resistant!
According to the watch serial number this Naiad was probably one of the very first produced in about 1937. Considering its about 85 years old it's in excellent condition. The case and case-back have only tiny dints and micro scratches although they may have been polished in the past. Original lead gasket still in place.
The dial displays a gentle, even patina with very few marks and even these are hard to spot without magnification. There is an outer railroad track index for the minutes and seconds and this "technical" dial is further indexed at fifth of a second intervals. Clearly not a standard model as the Arabic numerals are not simply painted on the dial but applied and riveted. Beautiful copper tone as can be seen in the pictures and the close-ups and matching the bezel although this is likely to have been made out of solid gold. Gold coloured Plume hands and a black seconds hand with its delightful counterbalance (see the magnified picture). The crystal has minor scratches and the crown has been replaced at some stage.
Inside, the Omega 23.4SC calibre is complete and fully operational. Sadly so many of this model are missing not only their seconds hand but also the mechanical drive mechanism. Both the movement and the case-back are fully marked Omega, as you would expect.
Comes with a used blue NATO style non-Omega strap. Not the one in the picture.
A relatively small watch by todays standards.
Overall a real piece of Omega Heritage.
