This timepiece masterfully blends vintage-inspired aesthetics with modern watchmaking, offering the wearer a reliable companion for both city streets and mountain trails.

- Screw-down crown and 200-metre water resistance for confident aquatic use

- Anti-reflective sapphire crystal for scratch resistance and clear legibility

- Internal rotating compass bezel controlled by the crown at 4 o'clock

- Classic green sunburst dial with luminous hands and applied indices for low-light readability

- Date window with cyclops magnifier at 3 o'clock

- Brown calfskin leather strap with crocodile-embossed pattern and three-fold clasp with push-button release

- Stainless steel case, 39.5mm diameter, with polished and brushed finishing
