Stepping up in the same colour and case shape
At 27mm this sits firmly in the tradition of the dressed watch worn close to the cuff — small enough to read as jewellery, the gold PVD case catching light without insisting on it. The guilloche pattern on the silver dial gives the surface something to do in changing light, and the applied gold indices keep the whole thing coordinated rather than busy. Black leather against gold is a long-established pairing for good reason, and at 6.85mm the watch lies flat enough that a sleeve does not notice it.

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 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 comparedIs it a men's or women's watch?
Listed as women's.
