The Mondaine Helvetica No1 Black Green Watch is a modern, Swiss-made timepiece that combines precision with sleek minimalism. Powered by a RONDA 715 HH2 quartz movement, it sits in a slim 40mm black stainless steel case with a low-profile 9mm thickness. A sapphire crystal protects the black dial, giving you clarity and resistance to scratches, while the solid caseback and gasket crown ensure everyday durability.

The dial is classic Mondaine — a clean black base with white hour and minute hands and a black sweeping second hand, offering both contrast and continuity. The watch is paired with a black leather strap that features a unique green leather lining, adding a pop of personality only the wearer sees. It’s finished with a matching black stainless steel pin buckle for a cohesive, understated look.

Ideal for professionals, creatives, and minimalists alike, this watch is the kind of quiet luxury you’ll want on your wrist every day. It’s functional, fashionable, and unmistakably Swiss.

Can I wear it in the rain? Yes — the watch is water resistant to 30 metres, making it splashproof for everyday life.

Is it too formal for casual wear? Not at all. Its clean design and comfortable strap make it perfect for both relaxed weekends and office days.

Does the green lining show? Only slightly — it’s mostly visible from certain angles, giving it a subtle, stylish edge.

Is the dial easy to read? Absolutely. The high-contrast hands on a matte black dial make time-checking simple and fast.
