Condition Assessment
Overall Condition: Pre-Owned - Excellent. This watch has been maintained to a very high standard. The stainless steel case shows only minimal surface swirling on the high-polish areas, consistent with light and careful wear.
Dial, Hands, & Crystal: The blue Aventurine dial is flawless, with its metallic inclusions sparkling vividly under light. The leaf-shaped hands are pristine, and the curved sapphire crystal is free of any marks or chips.
Case & Bezel: The 42mm case retains its sharp, fluid lines and signature scalloped case flanks. The polished bezel and brushed surfaces remain crisp with no notable dings.
Strap/Bracelet & Clasp: The watch is accompanied by its original midnight blue alligator strap, along with additional straps included in the set. The original Moser-engraved steel pin buckle is in excellent condition.
Technical Specifications
Reference: 1801-1201
Case Size: 42mm
Case Material: Stainless Steel
Dial: Blue Aventurine (Concept Style)
Movement: Calibre HMC 801 (Manual-Wind Manufacture)
Power Reserve: 7 Days (168 Hours)
Water Resistance: 30m (3 ATM)
Notable Details: Astronomical moon phase accurate to one day every 1,027 years, power reserve indicator on the movement side, interchangeable Moser escapement, and a small central hand acting as a 24-hour day/night indicator.
What Makes the Endeavour Perpetual Moon Special
The H. Moser & Cie. Endeavour Perpetual Moon Concept Aventurine is the ultimate poetic complication. While most moon phases are small sub-dials, Moser utilizes a large, high-precision disc at 6 o'clock that tracks the lunar cycle with such accuracy that it requires adjustment only once every millennium. By choosing the "Concept" dial, Moser removes all branding, allowing the deep blue, shimmering Aventurine glass to serve as a literal window into the cosmos.
Beyond the aesthetics, the HMC 801 manufacture movement is a beast of horological engineering. It boasts a massive 7-day power reserve, thanks to its double-barrel system, and features the brand’s unique interchangeable escapement module—allowing for faster and more efficient servicing. This specific reference is exceptionally rare; while Moser produced a similar version in red gold, the stainless steel execution was limited to a mere 50 pieces worldwide, making it a highly collectible "grail" for those who appreciate Moser’s "Very Rare" philosophy.
