You want a guillochéd rotor under a closed case back? No, no one does that.

There would be no point. The Breguets from that time with closed caseback don't have guilloché on the rotor. I guess you could pay Breguet for one now.

However, the rotor is likely 18k gold, based on the gold rotors of other Breguets with closed casebacks from the same period.

In terms of servicing, Breguet can service a movement from any time in their history (like AP and unlike Patek--who had to ask AP for help on a complicated pocketwatch in the PP museum). Since the movement is still in use and has been upgraded, maybe it would be possible, but expect a large cost as the idea that it would be easy to do so may be simplistic. It's possible there are some watchmaking issues involved that would complicate the task and expense, if Breguet would offer to do it at all.

. Lovely 7027, by the way!

Breguet 3130 / 3137

By: p-m-k : May 3rd, 2023-15:33

Hi all! As a very happy owner of the 7027, I am looking to add an early Breguet to my little collection. I have been drawn to the 3130 (white gold version) more and more lately. And inspired by the several posts on this forum. One information which still ...

Following.

Interested to read the comments too as I’ve been very Breguet curious the last while. I missed a great opportunity to acquire an earlier Tourbillion three or so years ago and I regret it. More recently I have been looking at the day date. And others that ...

The early Breguet Tourbillons…

… I find marvelous. I have been eyeing a ref 3350/7 or 3657. Which piece did you pass on?

I think the movement in the 3130 is also hand engraved and even chiseled ( rotor ). I don't think Breguet will technically update the movement, though.

I don't believe the 3130 has an engraved movement but probably a nice rotor...only the 3137 has the fully engraved movement.

I know about the 3137, but I don't see the point not to engrave the rotor or to go for a different finishing depending of the see through or solid case back. But I might be wrong.

There is a 3310, a perpetual, for sale on C24.

One picture shows the movement and the rotor is a gold rotor with guillochet. The rest of the movement does not appear to be finished to the same level as a xxx7 reference is.

The rotor, I was quite sure it as at least guilloché. For the rest, thanks for the precision.

Nice spotting

By: p-m-k : May 4th, 2023-08:18

I would assume indeed the movement under the case back is like that opened perpetual, which I like! Thanks for spotting!
