Condition: Excellent
Reference: 1342-0100
Year: Circa 2015–2020
Box: Yes
Papers: Yes (Includes "Blank" Warranty Card)
Accessories: Full Set. Includes an aftermarket custom leather strap from Aaron Bespoke. The original H. Moser & Cie. 18K rose gold pin buckle is preserved and installed on the aftermarket strap. Note: The original factory alligator strap is not included.

Condition Assessment
Overall Condition: Pre-Owned - Excellent. The 18K rose gold case retains its beautiful, sculpted contours and has been maintained with extreme care. Because rose gold is softer than steel, there are very light surface hairlines present on the high-polish flanks, but no significant nicks or dings.
Dial, Hands, & Crystal: The matte black dial is flawless. The leaf-shaped (feuille) hands and applied dot/stick markers are in perfect condition. The convex sapphire crystal is clear and free of any scratches or chips to the AR coating.
Case & Bezel: The 40.8mm rose gold case is sharp. The "sculpted" case sides—a hallmark of the Endeavour line—are crisp. The exhibition sapphire caseback provides a panoramic view of the beautifully finished HMC 342 movement.
Strap & Clasp: This piece is paired with a premium, custom-made strap by Aaron Bespoke (Beauchamp). These straps are renowned in the collector community for their superior quality and unique textures. The original 18K rose gold Moser signed buckle is included and in excellent condition.

What Makes the Endeavour Big Date Special
H. Moser & Cie. is the "watchmaker's watchmaker," and the Endeavour Big Date is the perfect entry into their world. While most big-date complications use two overlapping discs that create a "step" in height, Moser’s Flash Calendar uses two superimposed discs—one for the tens and one for the units—resulting in a date window that is perfectly flush and legible.
Furthermore, the movement is a technical powerhouse. The Calibre HMC 342 is a low-beat, high-torque movement (18,000 VpH) that provides a massive 7-day power reserve via a double-barrel system. It features an interchangeable escapement module, allowing a watchmaker to swap the entire heart of the watch for a pre-regulated one during service, minimizing turnaround time. The pairing with an Aaron Bespoke strap elevates this particular piece, giving it a more personalized, artisanal feel that matches the independent spirit of Moser.
