...I'm not sure.
Hi Happy Wis, all,
it was my understanding that current geneva sealed movements usually bear only one "poincon". Of course the traditional method was one seal on one of the bridges and another one on the mainplate.
That's a normal way to sign movements - observatory movements for example always required to be signed the same way with a serial number: one ser. number on a bridge and the duplicate number on the mainplate.
For the potential typo/error - as I posted this info it was taken from the press release. If it's a typo - at least I'm not guilty
But I'll try to find the answer and come back later!
