The brand is a symbol of timeless elegance, drawing inspiration from aviation and the design of early pilot's watches.

It features an elegant round case measuring 40 mm in diameter and 11 mm in thickness. The round case is crafted from polished stainless steel, lending it excellent durability and a brilliant finish. The dial is topped with a K1 mineral safety crystal offering strong shock resistance, while a gray crown at 3 o'clock handles all central adjustments. Its knurled finish ensures a secure grip. This model features a snap-back case back, engraved and transparent, providing a water resistance of 5 ATM. This open-back design lets you admire the movement's mechanics in full detail.

The Dial

This elegant double-circle dial delivers optimal legibility every day. In gray, it features a circular brushed finish along the edge with a dotted minute track running between two delicately textured circles. Arabic numerals in a 12-hour format follow this track for easy time reading. They are set against a base adorned with clous de Paris guilloché, and above them sweep two black central hands - poire-style hands indicating minutes with the long hand and hours with the short one. For added functionality, a striated sub-dial is positioned at 5 o'clock with Arabic numerals in increments of 5 for the display of small seconds via the small black seconds hand. This refined and intricate dial also features an open-heart complication, subtly revealing the movement's gears beneath. Between 4 and 9 o'clock, it displays key information including the collection name, country of manufacture, and movement type. Finally, the brand's logo and name are placed just below 12 o'clock as a signature.

The Movement

This watch runs on a Miyota 82S5 automatic movement - a Japanese caliber celebrated for its precision and reliability. It operates at a frequency of 28,800 Alt/h and delivers vibration resistance alongside consistent functional accuracy. The movement features 21 jewels to minimize friction, a stop-seconds device, and offers a power reserve of approximately 42 hours.

The Strap

This timepiece comes with a black strap that pairs seamlessly with any outfit. Crafted from premium cowhide leather, it offers exceptional durability and suppleness. Its surface features crocodile-embossed patterns with tone-on-tone stitching for a refined look, and it wraps your wrist with effortless elegance. It measures 20 mm in width and 215 mm in length, easily adjustable thanks to its silver-tone pin buckle.

Water Resistance

With a water resistance of 5 atmospheres - equivalent to 50 meters - this watch is your first step into water-resistant territory. While it's not built for swimming, sport swimming, or scuba diving, you can safely forget to take it off in the shower. That said, our experts recommend keeping this timepiece as dry as possible to preserve its movement for years to come.
