Stepping up in the same colour and case shape

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

A 45mm stainless steel case in silver and rose gold bi-metal two-tone houses a black dial with subtle wave texture and luminous dot and baton hour markers. The unidirectional bezel gives it a dive-watch character, while a cyclops lens sits over the date window at three o'clock. At 11mm thick, the case wears with reasonable composure for its size. A two-tone Jubilee bracelet with a deployment clasp completes the look, and a screw-down crown supports the 100-metre water resistance rating.

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?

Yes. At 100m it is rated for swimming and snorkelling, though not for diving.

Water resistance explained

Will the glass scratch?

Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.

Sapphire, mineral and acrylic compared

Does 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 compared

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.

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

Listed as men's.

Has the price changed recently?

It's currently at its lowest recorded price since we began tracking it. It's ranged between £149 and £199, today it's £149.
