The GP03300-0105 movement is in-house made with a module for the complications on top of Girard-Perregaux’s base caliber. It operates at 4Hz (28,800 bph) and offers about 46 hours of power reserve. Of course, it is an automatic with the rear of the movement visible through the caseback sapphire crystal. In a sense, what Girard-Perregaux really did is take the theme of an exposed caseback and move it also to the dial-side of the watch.

I’ve been waiting for Girard-Perregaux to release a slightly larger version of the Vintage 1945 XXL with simple dials such as this. They do have larger versions of the case, but they are often paired with much more complicated movements and are relatively thick as a result. A grander version of this curved, relatively slim case would be really interesting and might perhaps offer a highly marketable non-round watch.

Attached to the Girard-Perregaux Vintage 1945 XXL Large Date And Moon Phases watch collection are attractive black alligator straps. These straps are elegant because they don’t have contrast stitching, but I still prefer rolled-edge straps a bit more that have no visible stitching. Overall, while these smoked sapphire crystal dial versions of the Girard-Perregaux Vintage 1945 XXL Large Date And Moon Phases are going to be more niche models, they add some serious coolness to an otherwise sober looking vintage-style watch collection.

Price for the Girard-Perregaux Vintage 1945 XXL Large Date And Moon Phases with transparent sapphire crystal dial watch ref. 25882-11-222-BB6B in steel is $16,000 and the ref. 25882-52-222-BB6B in 18k pink gold is $33,800. girard-perregaux.com
