About this OMEGA watch

OMEGA Seamaster Diver 300M 42 mm 210.30.42.20.06.002, reference 210.30.42.20.06.002, is a performance-led dive watch with the distinctive design language of the Diver 300M family. It pairs OMEGA’s Swiss watchmaking with the reference-specific design and technical details that distinguish this model.

The Omega Seamaster Diver 300M 42mm ref. 210.30.42.20.06.002 is a distinguished model within Omega's renowned Seamaster collection, offering a perfect blend of high-performance dive functionality and refined design. The 42mm stainless steel case provides a bold yet wearable presence on the wrist, combining both polished and brushed finishes that create a sleek, sophisticated look. The black ceramic bezel insert with a diving scale ensures durability and precision, while the classic wave-patterned dial, also in black, enhances the watch’s maritime heritage. Rhodium-plated hands and hour markers, coated with Super-LumiNova, ensure excellent visibility under various lighting conditions, making it easy to read both on land and underwater.

At the heart of the Seamaster Diver 300M 42mm is the Omega Caliber 8800, a self-winding automatic movement known for its precision and resistance to magnetic fields up to 15,000 gauss. This chronometer-certified movement offers a 55-hour power reserve, ensuring the watch runs reliably even after being taken off the wrist for a few days. The movement is equipped with a date window at 6 o’clock, further adding to the watch's practicality for everyday use. With its 300-meter water resistance, the Seamaster Diver is designed to withstand professional diving environments, while its screw-down crown and case back offer additional protection against water ingress, making it a truly capable tool for underwater exploration.

The Seamaster Diver 300M 42mm comes with a stainless steel bracelet that features a combination of brushed and polished links, providing both comfort and a sophisticated, dynamic appearance. The bracelet is also equipped with an adjustable clasp, offering an easy fit for different wrist sizes. For added versatility, the watch can be worn with a blue rubber strap, giving it a more casual, sporty look. A transparent sapphire case back allows wearers to admire the intricate inner workings of the Caliber 8800 movement, further emphasizing the watch’s high-end craftsmanship. Whether you're a professional diver or simply someone who appreciates outstanding watchmaking, the Seamaster Diver 300M 42mm offers an exceptional mix of durability, functionality, and timeless style.

For clients considering an OMEGA watch for sport, travel and water-focused wear, this reference offers the established character of the OMEGA Seamaster Diver 300M collection in a configuration specific to this model.

Testimonials

★★★★★

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.

We went to Golden Tree Jewellers yesterday to pick out a watch for my wife. Simon was very helpful, allowed us to try on many options and never pressured us on any sale. Simon is very knowledgeable and we appreciated his guidance. Thanks again!

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.

We went in looking for some watches and Joe was really helpful and knowledgeable about all the different watches that this location had. Joe is also genuinely a nice person to talk to and always takes the time to answer questions and explain everything. I would highly recommend this store for anyone looking to buy luxury watches.

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.
