The NATO or G10 (the order form code) strap was designed in 1973 for the British MOD and is famous for its resistance and staying power. The wide grey nylon strap has loops and is long enough to be worn over military uniform. The NATO strap has experienced a boom in civil watchmaking over the last 5 years and been so popular that you can now see it wrapped around the J12 case. We’re talking Chanel here so, naturally, the NATO strap is in large-scale black alligator with two brilliant-cut diamond-covered loops. The gems echo the 53 diamonds on the steel bezel and 8 indices dotted around the grey steel dial. The 33mm diamond-dust polished ceramic and titanium case houses a quartz movement which brings to life the hour, minute and second functions in the heart of the dial. Price: 16,450 CHF
