The Breguet Expérimentale 1, ref. E001BH/S9/5ZV features an innovative constant-force magnetic escapement and a tourbillon with a fast 10-hertz balance wheel ensuring maximum accuracy (precision certified in the scientific class: +/- 1s/day).

Some in-depth reviews can easily be found online, so I just want propose a quick photographic walk-through here.

What do you think of this watch?

Best, Emmanuel




The legibility of the regulator display does not seem to be optimal.





The design of the regulator display is inspired by the pocket watch ref. 3448.



According to Andrew Hildreth, in his article for i-m-magazine, the design is also reminiscent of the Montre produced by ex-Breguet artisan watchmaker Jean-Baptiste Viot.



The Breguet gold case measures 43.50 x 13.30 mm.



Here's the front face of the movement, calibre 7250, in a technical display version, without the crystal.



And here's the back side of the movement.



Here, the back of the movement with the case back of the watch.



The coin edged case profile.



And one last wristshot.

well ...

From a horological perspective, this is probably one of the most interesting watches of the past few decades. Unfortunately, it would only have received truly extensive coverage in the press if it had come from Patek or Rolex. When a less “hot” brand brings something exceptional to market, it somehow seems to be treated as less important. And that’s a shame, because this is objectively exceptional. That said, on a personal level… the looks are absolutely not for me. I simply find it ugly. Far to
