Allowances must be made for the fact that Omega did produce ‘specials’ - which didn’t follow the usual production. In spite of that, there are some surprising features:
1. The Omega 30’’’ movements were never signed. In my opinion, the Omega signature on the movement has been added (not difficult - I own one myself which has been similarly modified!).
2. The late Omega 30’’’ dials (later than this watch) were signed - but not with this font. In my opinion, this Omega signature has been added (not difficult). Unlike the ‘8 DAYS’ (which has been fired onto the enamel), this ‘Omega’ signature could be removed with spirits.
3. The minute hand is not original for an Omega 30’’’.
4. These watches were never gold plated - but of course a watch could have been specially prepared for a special customer. However, there are parts here which have been plated which would never usually be plated. Furthermore, since the watch is over 115 years old, it is surprising that there appear to be no scratches.
5. Even more surprising (in that case) are the scratches which appear on either the dial or the crystal (in the first image shown). That image is reproduced here with more contrast to show those scratches. If the scratches are on the crystal, it is presumably a plastic replacement (how could glass become so scratched on a watch that otherwise shows no scratches?). And how could even the plastic become so scratched?!
6. Regarding the (very elegant) work on the caseback, a prospective buyer is encouraged to look at the other (similar) items that the seller offers.
7. The movement appears to be original and in good condition. The Omega 30’’’ is not a rare watch - for a ‘regular’ (nickel-alloy) version in this condition, a seller might hope to get $500 - the $9,500 premium for the provenance claimed by the seller would therefore be worth checking!
