Three-bridge-Tourbillon follow up...going to the Year 1991
Friends,
a few days ago, I showed you the No. 1 Three-Golden-Bridge Tourbillon pocket watch from 1982. The first attempt to bring back the signature of GP of mechanical watches with a mind-blowing effort of ~1000 hours to complete the finishing.
In the early 90s, GP decided to bring the Three-Bridge Tourbillon into a wrist watch, but it was clear at that time that some changes had to be made. It was not feasible, production-wide and cost-wise to apply the same 1000 hour effort if you wanted to enter a small serial production of Tourbillon wrist watches.
Without compromising the quality of the polishing, GP opted to simplify the Bridges itself.
If you look at it side-by-side (or above and below) you can see that the wrist watch bridges are flat throughout and do not have that round inner shaft.
With these changes, GP managed to bring down to finishing effort to a mere 100 hours, still a lot of manual polishing, if you ask me, but much more manageable.
Here you see a very early Three-Bridge Tourbillon from 1991 in Platinum case and (unfortunately) diamond hour markers.
What is so important for this watch that it started an evolution of the three-bridge torubillon that today has various variations like the Neo Tourbillon or arched bridges.
Best,
CC

I think I could forget the diamond hour makers if you wanted to offer it to me for Christmas dear CC 😁
One of its cousins seen recently. Best wishes Alkiro ...
Thank you for this post, CC!
To change the Three Golden Bridges from Pocket Watch to Wrist watch was a important step in the GP history! Without that, who knows where the brand would have been today. One big difference we see on these early WW-versions of the TGB is that the bridges ...
Indeed it was a very important step
and very hard to imagine GP today without this iconic wristwatch. I fully agree with you on how the bridges are shaped and integrated in the PW versus the early WW, but the modern Le Esmeralda offers the best of both worlds CC
Thanks Mitch and yes
each bridge will easyly take several days of polishing, but on the Pocket Watch, 1000 hours is almost half a year of work (considering humane Swiss working hours)
