OMEGA Seamaster 300 41 mm 234.30.41.21.01.001, reference 234.30.41.21.01.001, is a heritage-influenced dive watch that connects modern OMEGA watchmaking with the Seamaster 300 legacy. It pairs OMEGA’s Swiss watchmaking with the reference-specific design and technical details that distinguish this model.
OMEGA first introduced the Seamaster 300 in 1957 - designed especially for divers and professionals who worked underwater. More than 60 years later, the timepiece has been completely upgraded with an enhanced form that is ready for a new generation of adventurers.
This 41 mmstainless steel model includes a black dial and a black oxalic anodized aluminium bezel with its diving scale filled with vintage Super-LumiNova. The recessed hour markers and open numerals feature Super-LumiNova, which is also present on the rhodium-plated hands.
Presented on an ergonomic stainless steel bracelet, this timepiece includes a transparent sapphire crystal caseback, enabling a clear view of the OMEGA Co-Axial Master Chronometer Calibre 8912.
For clients considering an OMEGA watch for sport, travel and water-focused wear, this reference offers the established character of the OMEGA Seamaster 300 collection in a configuration specific to this model.

Not your typical pretentious jewellery store or AD for watches, I walk in often chat with the sales people, look at watches with zero pressure or snobbery. They are open and inviting, all which encouraged me now to purchase from them as well. Can't go wrong.

Customer service received was excellent. They took the time to answer all of my questions and show me a fair amount of watches before I made my decision. Opted to buy two watches after a fair negotiation and left feeling very happy with my decision to shop at Golden Tree.

My favourite luxury watch retail store in the Lower Mainland. Bob, Aavis and their staff are very knowledgeable, patient and caring for their customers. I visit them multiple times a month when I am in the mall and they engage me regardless of me buying a watch or not. I've bought two watches from them and look forward to buying more. Highly recommend you visit them if you love watches or are curious about what to buy next for yourself or your loved ones.
