The F.P. Journe Centigraphe Souverain represents the brand s approach to chronograph complications within the Souverain collection. This reference features the specialized caliber 1506 movement and carries the distinctive Centigraphe designation, positioning it as F.P. Journe s chronograph offering in their manual-winding lineup.
The 40mm case is crafted from 18k rose gold and fitted with a sapphire crystal. The silver dial provides the backdrop for the chronograph functions. The manual-winding caliber 1506 movement delivers an 80-hour power reserve. Water resistance is rated to 30 meters, and the watch is completed with a leather strap. The fixed bezel maintains clean proportions around the case perimeter.
This reference appeals to collectors seeking F.P. Journe s interpretation of chronograph mechanics in precious metal construction. Production began in 2007, establishing this as part of the contemporary F.P. Journe catalog. The Centigraphe attracts those interested in independent watchmaking combined with traditional manual-winding chronograph complications, offering substantial power reserve within the 40mm rose gold case format.
that AP perpetual is my favorite of the bunch👍. The FB is a strong second.
But, I got to admit, if I could just grab one and not look back, it would have to be the F.B. - that octagonal case with the movement and spectacular finishing/details would keep my love affair going endlessly
Great Idea; I really like the AP and the VC A propos metals: maybe distinguish between the various grades of titanium? Maybe also between the white gold (with coating) likepatrk before 2000 vs the grey gold (massive, no coating) like patek after 2007? Best Jerome
It’s blue - grey The Delaloye is a nice watch but the tantalum looks less blue So a weak spot for the tantalum journe But … platinum is sooooo good I think I like all the material you mentioned 😀
I'll opt for the plat. Roth, quattro.
These two watches are not my kind because I don’t respond to the openwork aesthetic, but of course I understand their appeal. Best, Emmanuel
