With an injection of vivid colours or an edgy aesthetic, the world's finest names in horology present their summer must-haves, from Zenith's Elite Lady Moonphase and Chanel's J12 XS to the IWC Portofino and Richard Mille's Rafael Nadal homage. Here's why you need them now...

Zenith's Elite Lady Moonphase

The ultra-thin 33mm stainless steel case gets a dose of bright summer-appropriate colours –yellow, apple green, turquoise and red – to add playfulness to a showcase of technical mastery. The eye-catching dials are also complemented perfectly with a matching alligator leather strap.

Richard Mille's RM 27-03 Rafael Nadal

Rafael Nadal, the record-breaking victory at the recent Roland Garros, has a timepiece that befits his sporting legend status: the RM 27-03. With a choice of bright and abstract red and yellow tones on the case, the watch demands attention aesthetically while the skeletonised dial depicts a bull head, the symbol of both Spain and Nadal. As well, the crown mimics the shape of a tennis ball, reflecting Nadal's dominance on the court.

IWC's Portofino

The Portofino Automatic Moon Phase 37 features an 18-carat red gold case and a total of 78 diamonds – 66 on the bezel and 12 on the dial – with a Milanaise mesh bracelet in matching red gold to elevate the level of sophistication to a much-loved line from the maison.

Chanel's J12 XS

While a highlight of the first edition of the J12 XS was the cuff with silver piping, this new iteration shines the spotlight on the diamond-filled bracelet, adding to the blurred line between watch and jewellery. Available in cool monochromatic hues, the J12 XS offers a more minimalistic, but no less luxurious, take on summer watches.

Roger Dubuis' Excalibur Essential 36

A sun-brushed finish alongside the crisp clean dial combines to create an aesthetic that reflects both horological mastery and seasonal flavours. Encasing the bezel are 48 brilliant-cut diamonds, further enhancing the rose gold indexes on the dial. Meanwhile, the date complication is located at the 6 o'clock position, while the purple alligator leather strap rounds off the elegant yet edgy look.
