H. Moser 1344-0504

Is one of the brand’s most distinctive interpretations of the perpetual calendar, pairing a dramatic yellow-green fumé dial with a lightweight DLC-coated titanium case. Reference 1344-0504 combines Moser’s minimalist display philosophy with the technically sophisticated manually wound HMC 341 perpetual-calendar movement.

Yellow-Green Fumé Dial

The defining visual feature of the H. Moser 1344-0504 is its yellow-green fumé dial. The color transitions subtly across the dial depending on the lighting, creating the characteristic depth associated with Moser’s fumé finishing.

Rather than filling the dial with conventional calendar indications, Moser uses a restrained display that keeps the watch visually clean while retaining the information required for a perpetual calendar.

The large date indication provides an immediate reading of the calendar date, while a small central hand works with the hour markers to indicate the month.

DLC-Coated Titanium Case

The 40.8mm case is manufactured from titanium and finished with a black DLC coating. This creates a dark technical appearance while keeping the case relatively lightweight.

The Endeavour case features Moser’s characteristic curved profile and sculpted lugs, with sapphire crystal protecting the dial and a sapphire display back providing a view of the movement.

The watch is fitted with a black alligator leather strap and a matching DLC-coated titanium tang buckle.

HMC 341 Perpetual Calendar Movement

At the heart of the Endeavour Perpetual Calendar 1344-0504 is H. Moser & Cie’s manually wound HMC 341 calibre.

The movement uses a double-barrel construction and provides a minimum power reserve of seven days, or approximately 168 hours.

Moser’s perpetual-calendar architecture is designed to provide a clean display while automatically accounting for the different lengths of the months and leap years. The leap-year indication is positioned on the movement side, allowing the front of the watch to remain remarkably uncluttered.

A Minimalist Perpetual Calendar

One of the defining characteristics of the Endeavour Perpetual Calendar is the way Moser approaches a traditionally complex complication.

Instead of displaying numerous calendar windows and subdials, the watch concentrates the information into a large date display, a central month indicator and the discreet leap-year indication visible through the sapphire caseback.

This approach gives the H. Moser 1344-0504 a distinctive balance between traditional high horology and contemporary minimalism.
