There are demonstrative whirlpools, made to shine. And then there are those who talk to those in the know.

H. MOSER & CIE. ENDEAVOUR TOURBILLON BLUE LAGOON 38 mm – Red gold and Blue Lagoon for a contemporary icon
When Swiss watchmaking refinement meets the poetry of movement
The H. Moser & Cie Endeavour Tourbillon Blue Lagoon is much more than a watch: it is a work of horological art designed for those who seek exclusivity, elegance and innovation. Produced in a contemporary 38 mm diameter, this 5N red gold watch embodies a new vision of luxury, discreet yet intensely expressive.
Its Blue Lagoon fumé dial, with its vibrant color that changes with the light, immediately catches the eye. As always with H. Moser & Cie, there is no ostentatious logo, no superfluous hour markers: here, purity reigns supreme, in order to highlight the essential. And the essential is this flying tourbillon at 6 o’clock, a true mechanical feat, which seems to float above the dial, suspended in time.
A manufacture movement on a par with the design
At the heart of this creation beats the automatic HMC 804 caliber, developed entirely in-house. Equipped with a bidirectional winding system and a double balance spring designed by Precision Engineering AG (a company of the Moser group), this movement guarantees remarkable precision and a 72-hour power reserve. The tourbillon, beyond its beauty, improves the regularity of the movement, even in a vertical position.
A perfect balance between tradition and modernity
With its organically curved case and meticulous hand-finished details, the Endeavour Tourbillon Blue Lagoon illustrates H. Moser & Cie’s ability to combine traditional watchmaking expertise with sleek contemporary design. Every detail, from the mirror polish of the case to the transparent sapphire crystal case back, is designed to appeal to the most demanding connoisseurs of fine watchmaking.

MOVEMENT
The HMC 804 is a self-winding movement with tourbillon that compensates for the effects of gravity in two ways: thanks to the one-minute flying tourbillon and the patented double balance spring comprising two identical balance springs that compensate for any positional error.
