Moonphase complications under €10,000, from Frederique Constant's manufacture moonphase to Grand Seiko's Spring Drive moon. The most decorative of the useful complications.
A standard moonphase uses a 59-tooth disc that advances one position per day, completing the lunar synodic month (29.53 days) in approximately 59/2 = 29.5 days. This drifts ~1 day every 2.5 years. "Astronomical" or 122-year moonphases use a more accurate gear ratio that drifts only 1 day per ~122 years; some manufacture moonphases (Lange Saxonia Moonphase, Patek 5396) use this design.
Under €10,000 the moonphase market is unusually well-served: Frederique Constant builds in-house at €2,500-3,000, Longines Master moonphase chrono sits at €3,500, and Grand Seiko Spring Drive moonphase tops the bracket at ~€8,500.
In-house manufacture moonphase at €3k.
Frederique Constant's Cal. FC-705 is built at the brand's Plan-les-Ouates Geneva facility: automatic moonphase + date, 38-hour reserve. The price/spec ratio is unmatched among Swiss-made manufacture moonphases.
Old-school moonphase chrono with column wheel.
Longines's Master Moonphase Chronograph uses the L687 (an evolved column-wheel chronograph with calendar and moonphase). Triple-calendar layout: day, date, month, plus moonphase. Heritage-leaning aesthetics.
Spring Drive moonphase with photographic moon.
Grand Seiko's SBGY-series Spring Drive moonphase uses a photographic image of the moon (not a stylised face) on a striated dial. ±1 sec/day, 72-hour reserve.
Triple-calendar moonphase with German Bauhaus design.
Junghans's Meister Kalender combines triple-calendar (day, date, month) with moonphase, J800.3 ETA-derived movement. The clean Bauhaus-inflected dial separates it from standard Swiss moon-and-date complications.
€900 mechanical moonphase. Yes.
Tissot's Le Locle Moonphase is the under-€1k mechanical moonphase entry. Powermatic 80 base movement, 80-hour reserve. The cheapest legitimate Swiss moonphase.
Open-heart moonphase under €1,500.
Hamilton's Jazzmaster line gets a moonphase + open-heart configuration showing the regulator below 6 o'clock. ETA-based H-37 movement.
Microbrand 122-year astronomical moonphase.
Christopher Ward's C9 Moonphase uses a 122-year astronomical gear ratio (drift 1 day per 122 years vs the standard 2.5 years). The CW JJ04 module adds the moonphase to a Sellita SW200 base.
Just over budget but the Villeret moonphase reference.
Blancpain's Villeret moonphase has been the brand's signature reference since the 1980s. Cal. 6654, 100-hour reserve, full triple-calendar with phase.
Listed for context; the modern moonphase landmark.
H. Moser's Endeavour Perpetual Moon uses a fumé dial and a moonphase accurate to ~1,027 years. Over budget but the modern moonphase visual reference.
Mido's quiet moonphase pick.
Mido's Multifort Patrimony Moonphase uses the brand's Cal. 80 base with moonphase module. Sunray dial, applied indices, 80-hour reserve.
Best price/manufacture combo: Frederique Constant Slimline Manufacture Moonphase. Best heritage chrono-moonphase: Longines Master. Best dial: Grand Seiko SBGY. The moonphase style hub tracks news.
