WATCHES: FORMULA 1 PARTNERS

Bell & Ross BR 03-94 RS17

Price: `4.33 lakh From: bellross.com

To mark its second year as a backer of the Renault Sport Formula 1 team, Bell & Ross has launched this limited-edition-of-500 model. It has the familiar B&R instrument-inspired case, here in matt black ceramic and measuring 42mm

across. Inside are an automatic movement and a carbonfibre dial, while yellow highlights, including an anodised aluminium start/stop button for the chronograph, reinforce the link to

the French racing team.

Richard Mille RM 50-03

Price: `9 crore From: richardmille.com

McLaren sponsor Richard Mille claims this is the lightest mechanical chronograph ever. Its 44.5mm case, created with help from McLaren Applied Technology, is machined from 600 layers of Thin Ply Technology carbon impregnated with a resin containing graphene – a nanomaterial six times lighter than steel but 200 times stronger.

Add a lightweight movement and the whole caboodle weighs just 38g. But it also costs more

than a P1 did new…

Edox Chronorally Sauber F1 Team Price: `1.25 lakh From: edox.ch

This watch from Sauber partner Edox features smatterings of the Swiss team's signature blue colour, while inside its 48mm titanium case is a carbonfibre dial and a quartz movement with a ‘split seconds' function. This means two chronograph seconds hands run together, one superimposed over the other, but one can be stopped independently to allow an elapsed time (a lap time, say) to be accurately observed while

the other hand continues timing.
