I have seen Patek Philippe pocket watches with guilloche dials in the past but those tend to date more toward the 1910s https://www.luksusure.org/category/replika-iwc/ and aren't so obviously inspired by Breguet. Check out a few examples of these earlier watches here, here, and here. The one we are focusing on here dates to the 1940s and has https://www.rolexrelogios.to/produkt-kategori/yacht-master/ more overtly Breguet dial cues, like the outer minute track and the sub-seconds register styles. https://www.replicarolexorologi.co/categoria-prodotto/yacht-master/ It's worth noting that the Patek signature is correct for the second half of the 1940s with "& Cie."
