Stepping up in Roamer's range
The Monza 100 name borrows from motorsport, and the collection carries that brief consistently: a chronograph built to be used, not just worn. Roamer has been making watches in Switzerland since 1888, and the Monza line sits within that tradition as a functional sports piece rather than a dress watch with borrowed credentials. The 48mm lug-to-lug span is notably compact for a 42mm case, which means it seats flat against the wrist rather than bridging it, and the 12mm thickness keeps it civil under a cuff. The sunray green dial shifts between deep forest and something closer to olive depending on the light, with the three chronograph subdials arranged across it without crowding. The Ronda 5030.D driving it is a Swiss-made quartz chronograph movement with a strong reputation for accuracy and battery longevity — the kind of calibre that runs quietly for years without attention. The steel bracelet is a genuine match for the case in finish, and the push-button deployant makes sizing straightforward.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Yes. At 100m it is rated for swimming and snorkelling, though not for diving.
Water resistance explainedWill the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Sapphire, mineral and acrylic comparedDoes it need a battery?
Yes. It is quartz, so expect a battery change every two to three years at a jeweller.
Quartz, automatic and solar comparedWhat size strap does it take?
22mm. Any strap of that width will fit, and on most modern watches quick-release bars make the swap a two-minute job with no tools.
Will it fit my wrist?
Lug-to-lug is 48mm, which suits wrists from roughly 16.5cm (6½ inches) upward.
Lug-to-lug decides fit more than case diameter does.
How to size a watch to your wristIs it a men's or women's watch?
Listed as men's.
