Pink leather and a diamond-set dial make the Mido M024.207.16.036.09 a watch with a sense of fun, but there is nothing frivolous about what is inside. This is a Belluna II Lady, and it runs on Mido's Caliber 80, an automatic with up to 80 hours of power reserve, a rare feature in a 33mm women's watch.

The Belluna collection, introduced in 2008, takes its inspiration from London's Royal Albert Hall, and its round case and clean, symmetrical dial have a calm Art Deco poise. Here, a light dial with diamond hour markers and a date window sits in a polished steel case under sapphire crystal, while the transparent caseback reveals the movement at work. The pink strap brings softness and color, and it can be swapped for black or white leather whenever you want a different mood.

At under 10mm thick, the Belluna II Lady wears close to the wrist and pairs easily with bracelets. It is an easy everyday companion, dressy enough for evenings and relaxed enough for weekends.
