5. Breitling Superocean

The original incarnations of the Superocean were launched by Swiss watchmakers par excellence Breitling in 1957. Now, over half a century later, Breitling has again revamped their ultra tough maritime showpiece. Water resistant to 1,500 meters (a bends-inducing 5,000ft), the watch features sapphire crystal glare-proof casing and is available with black, silver, blue, red or yellow dials, either with the 'diver pro' rubber strap or 'ocean racer' steel.

Price: £2,000 (rubber); £2,300
