GP?s older Richeville chronographs, ref. 2710/2750
G'day,
in order to answer a recent question and for what it?s worth, a few notes on two older models.
The predessors of the current Richeville range included two chronograph models; each of them could be had with different case materials (steel, two-tone, solid gold) and different dials, which made for a nice variety then.
Basically the different models were made roughly between 1994 and 1999; there are two base references, ref. 2710 and ref. 2750.
Reference 2710 was a manual wind chronograph:
The movement is a GP-reworked (finished, decorated and assembled by hand) Lemania 1872 chronograph ebauche (with central seconds counter, 30min-counter in a sub register and permanent small second).
This is a very classic cam/lever (as opposite to column wheel) solution and quite famous itself; probably the best known watch to sport a likely movement is Omega?s Speedmaster Professional manual wind watch (aka Omega calibre 861).
Interestingly there?s a small number of other GP chronographs sporting the same movement, such as the beautiful ref. 7750 chronograph with an interesting 34mm case. These models are among the rarest of GP since 1990?s.
Reference 2750 was an automatic chronograph:
This watch featured an automatic module chronograph based on an ebauche by ETA.
A question frequently asked is how to separate both.
There are two details which are easy to catch:
- Reference 2750 says "automatic" on the dial, reference 2710 "Richeville" instead
- Reference 2750 came with square-shaped pushers, reference 2710 with round pushers.
So it?s likewise easy to tell, although none of these comes with a transparent back.
From what i recall, the manual wind variant was made in lower quantities and is a little more tricky to find.
Both are not the rarest of GP?s models, but interesting watches nonetheless.
Greetings from germany,
