Jacques Bianchi Marseille’s JB300 Marks the Latest Update of Its Legendary Dive Watch
Featuring the iconic teeth-like bezel.



Independent French watch brand Jacques Bianchi Marseille has released the JB300 Diver, an updated iteration of its legendary military dive watch. The brand made its launch in 2021 where it introduced the works of watchmaker Jacques Bianchi to the wider public. Bianchi’s watches have a history that dates back to the early ‘80s when he was known for producing timepieces for the French military divers.
As hinted in its name, the JB300 offers 300 meters of water resistance, solidifying its status as a professional-grade diver timepiece. Housed in a 42mm stainless steel case, the watch features a black “maxi dial” with a 3 o’clock date, geometric-shaped indices alongside 24-hour markings in red. The indices and handset are coated in a luminescent coating that emits a green glow in dark environments.
The oversized and teeth-like bezel is one of its defining design features that has been faithfully replicated from the original ‘90s model. It’s geared with 40 hours of power reserve and runs on the P24 Swiss automatic mechanical movement. Completing its sporty appeal, the watch is paired with a perforated rubber strap from Tropic.
Priced at €741 EUR (approx. $782 USD), the JB300 Diver watch is currently available for pre-order via Jacques Bianchi Marseille’s webstore, for a limited period of 15 days.
