John Arnold was an exceptional watchmaker who had several major patents to his name and created a minor storm in precision timekeeping with the Arnold No. 36. This was the first-ever watch referred to as a 'chronometer', a term used to this day to denote a supremely accurate timepiece. The TB88 is compelling proof that the brand has lost none of its appetite for innovative technology or precision timekeeping, all encompassed in distinctive English design for the Royal Collection.

The present version has a rose gold case and is powered by the black-finished version of caliber 5003.
