Editor's Notes

Since its foundation, Ulysse Nardin has had a singular vision of innovating marine choronometers to ensure the highest performance. Water resistant to 300m depths, this titanium 'Diver' watch is powered by an automatic chronograph calibre UN-150 movement, conceived and developed in-house at the Swiss factory with 322 components. It includes an ingenious silicon hairspring that the watchmaker pioneered - the team describes it as taking ""precision to extremes"". It has a durable rubber strap and concave bezel.

We offer a two-year warranty for all working parts and manufacturing faults for luxury watches. For more information, contact one of our experts by emailing watches@mrporter.com
