Rotary Lumen 40mm Mens Watch Green

Premium

Sits in Rotary’s upper tier here — more premium than three quarters of the Rotary watches we list, which start at £76.

Price range £76 to £349 across 169 Rotary watches in stock.

The 40mm stainless steel case combines brushed and polished surfaces, with angular edges and integrated lugs that taper into a multi-polished three-link bracelet. A domed bubble mineral crystal sits above the dial, giving the profile a vintage curve, while an exhibition caseback reveals the Miyota 8215 rotor beneath. The dial carries a textured, stone-like green finish that shifts in the light, with baton indices and a date window at three o'clock. Lug-to-lug measures 47mm, and the bracelet fastens with a push-button deployant clasp. Water resistance stands at 50 metres.

Learn more about Rotary

Moise Dreyfuss started Rotary in La Chaux-de-Fonds in 1895. Within a generation his sons Georges and Sylvain had opened a London office and begun exporting to Britain, which turned out to be the decision that defined the company: Britain became, and remains, Rotary's most important market.

The winged wheel logo arrived in 1925 and has barely changed since. It became familiar enough in British high streets that the brand is widely taken for British, despite the Swiss origin.

Rotary supplied watches to the British Army, and the wartime and post-war association gave it a foothold in a market where an affordable, dependable Swiss watch was exactly what most buyers wanted.

The family held the company for over a century, making it for a long time the oldest family-owned Swiss watchmaker still trading. Ownership passed to Hong Kong's Citychamp in 2014, and in February 2025 to the UK's Peers Hardy Group.

The modern range sits at the accessible end — quartz and automatic dress watches, divers and chronographs, with the Henley, Windsor and Legacy lines carrying the collection.

Frequently asked questions, and things you should know about this watch

Can I swim with it?

Showering yes, swimming no. 50m covers splashes and brief immersion, but a swimming stroke generates well above the pressure that figure describes.

Water resistance explained

Will the glass scratch?

It can, over time. Mineral glass handles daily wear but will pick up fine scratches that sapphire would not.

Sapphire, mineral and acrylic compared

Does it need a battery?

No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.

Quartz, automatic and solar compared

How long does it run for when it's not worn?

About 42 hours fully wound — enough to survive a night off the wrist, but not a full weekend.

What 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 47mm, which suits wrists from roughly 16cm (6¼ inches) upward.

Lug-to-lug decides fit more than case diameter does.

How to size a watch to your wrist

Is it a men's or women's watch?

Listed as men's, though at 40mm it sits in the range that suits anyone.
