The watch is powered by the L888.5 caliber, a high-performance self-winding mechanical movement. The movement operates at a frequency of 25,200 vibrations per hour, features an anti-magnetic monocrystalline silicon hairspring, and provides an extraordinary power reserve of approximately 72 hours.

The round stainless steel case features a versatile diameter of 39.00 mm, a thickness of 9.40 mm, and a lug-to-lug width of 46.10 mm. Protected on the front by a scratch-resistant sapphire crystal with a multi-layer anti-reflective coating on both sides, it reveals the beauty of the movement on the back through a transparent sapphire crystal case back. It is water-resistant to 3 bar and weighs a total of 71.0 g.

The dial features a traditional blue “barleycorn” geometric pattern. The applied Arabic numerals and polished silver hands stand out clearly against this geometric surface. The date window is positioned at 3 o’clock.

The strap is a deep blue, crafted from fine alligator leather on the front and calfskin on the back (20 mm wide at the lugs). It pairs beautifully with the dial’s color scheme, offering a comfortable and extremely sophisticated wearing experience.
