Complete Calendar Display
The watch shows time, date, and month on a clear dial. This complete calendar eliminates the need to check your phone for the date, a practical feature for work or travel. The date window is easy to read at a glance, supporting punctuality throughout the day.
Hollow Tourbillon Design
The hollow tourbillon adds a visible rotating component that showcases the mechanical movement. While its primary role is accurate timekeeping, the visual effect makes the watch a talking point. It is a feature often sought by enthusiasts of mechanical watches.
Size and Fit

The dimensions are designed to suit everyday wear while maintaining a masculine presence on the wrist.
42mm Dial and 16mm Case
The 42mm dial diameter provides a clear view of the time, date, and month. The 16mm case thickness gives a solid feel without being overly bulky, fitting comfortably under most shirt cuffs.
20mm Leather Band at 24cm Length
The 20mm band width offers a balanced look, while the 24cm length accommodates varying wrist sizes. The buckle clasp allows easy adjustment. The leather material develops a natural patina over time, adding character with regular use.
Durability and Care

3Bar Water Resistance
Water resistant to 3Bar, the watch can withstand splashes of water or brief rain exposure. It is not suitable for swimming or showering. Avoid pressing the crown or buttons when wet to maintain seal integrity.
Hardlex Dial Window
The Hardlex mineral crystal resists scratches from incidental contact, keeping the dial clear over time. Regular care such as wiping the case with a soft cloth helps preserve its appearance.
