I have to come with a longer elaborate as I am at my wits end with this one: Olma 1960s model Olma Sport.
Some time ago, I got this watch at a decent horological market as NOS. Optically, it is in absolute prime condition, like factory released. The thin scratch on the back was my own mishap.
Technically, is shows a performance on the timescale/timegrapher equal to any prime brand: + 0 to + 5 secs/day, 0 beat error, amplitude of 314 (measured with correct lift angle for this movement). Frequency is 18.000 A/h. Naturally, it keeps time extremely well.
Now, that is a nice find one could say, but I am not convinced it is truly vintage, however extremely well made.
Olma was (is?) a small watch brand, Olma = Numa Jeannin SA, Fleurier, Switzerland, registered on Jan. 22, 1926. The ‘Olma Sport’ logo was registered on March 21, 1961.
The movement is marked FHF ST 96, a fairly standard and often produced model from FHF - Fabrique d'Horlogerie de Fontainemelon.
If the watch would be from the 1960s, even unused, it could not have such an excellent performance (dried in oils etc.). It is also not the typical collectors watch which is left in the drawer. The FHF 96 (marked as such or not) is an often cloned movement, especially in Asia.
The original company had disappeared some day, but as I understand only well after the years after the quartz crisis. Everything is a little bit in the dark from there, but in 2005, the brand was re-launched with the support of Hengdeli International Group, Hong Kong, the world’s largest watch retail group for international renowned brands (according to their own statement). Besides the Zhang family, there are other shareholders like the Swatch Group or a large Chinese re-insurance group, so that sounds like a very solid base. All watches are marked ‘Swiss Made’ (to whatever extend), and that can’t be fake with the Swatch Group amongst the shareholders.
Some experts I had contacted told me, that it could very well be, that the new owners got at least some original parts from the factory’s stock and that the watch would really quality as new old stock, at least made from new-old parts. A company with shareholders like the Swatch Group or a large re-insurance group would certainly not cheaply fake or clone outdated FHF movements. Perhaps they have been re-manufactured according to old standards, but in this case, why bother with something like a run-off-the-mill FHF ST 96?
The original Olma Sport had the original FHF ST 96 inside (and other variants with date), but the ones I have seen all have an incabloc shock protection, this one here looks like KIF.
Any opinions on that?
