Bell & Ross is renowned for creating instrument watches designed as quality tools for professional divers. Other features require the watch to be operationally tested underwater at a depth of 30 cm (+/- 2 cm) for 50 hours, within temperatures between 18°C and 25°C. At the end of this testing period, the mechanisms must still function correctly. Watches are also tested to ensure they are not sensitive to thermal shock, that they resist overpressure in water, and that condensation does not form under various conditions.
The much-sought-after BR 03 Diver turns seven this year, and with it come changes that divers will appreciate. These changes include a ceramic insert and movement that guarantees increased durability and a power reserve of 54 hours. The watch runs on the BR-CAL.302-1 automatic winding mechanism, beating at a frequency of 28,800 alternations per hour (4 Hz). All BR 03 DIVER watches are water-resistant to a depth of 300 meters.
Aesthetically, the watch now features a new typography and redesigned hands for optimal legibility, even in challenging underwater conditions. Carlos Rosillo, President, and co-founder of Bell & Ross, says that the new BR 03 DIVER watches comply with the international ISO 6425 standard, which specifies that a watch must withstand submersion in water to a depth of at least 100 meters and must have a time monitoring system. Furthermore, watch markings must remain visible from 25 cm in the dark underwater.
