On Holden’s list, Probably Want At Some Point
Frédérique Constant Classics Carrée Calendar Moonphase
The Frédérique Constant Classics Carrée Calendar Moonphase (FC-265S4C6) is a complication watch from Frédérique Constant: a 30 mm stainless steel case, 8.01 mm thick, with a quartz FC-265 movement and 30 m water resistance.
Its lug-to-lug length is unknown, so wrist fit can only be judged from the 30 mm case width.
Research found it at $1,395 list in the US (checked August 2026).

Will it fit?
The research didn’t find a sourced lug-to-lug length for this watch, so the fit can’t be estimated here. If you can measure one, try it in the wrist-fit tool.
What the research found
These are the research’s judgments, scored against Holden’s priorities, not his own words.
Strengths
- Genuinely different shape — Art Deco rectangular case in a collection of round tool watches
- Full calendar (day, date, month) plus moonphase at an accessible price
- 8.0 mm thin with convex AR sapphire — slides under any cuff
- 60-month battery and ±15 s/month quartz practicality
Weaknesses
- 3 ATM / splash-resistant only — special-occasion construction
- Quartz module long-term serviceability depends on FC stocking replacements
- Gold-plated FC-265S4C5 variant carries plating wear-through risk over decades
- Configuration unresolved — dial/case-tone choice still open
