Seamaster Diver 300m - an updated icon 42mm case in stainless steel paired with a blue rubber strap Summer Blue ceramic dial with the collection's wave design and a gradient finish Blue ceramic bezel with a summer blue enamel diving scale Powered by a Master Chronometer calibre 8800 movement AN UPDATED ICON Since 1993, the Seamaster Diver 300m has enjoyed a legendary following. To mark 25 years since its release, the collection has been beautifully updated from the inside out, updating the materials and technology while retaining the original design and ocean spirit. Available in both 42mm and 43.5mm, the new models are all powered by Master Chronometer calibres for extraordinary precision, performance, and magnetic resistance. SUMMER BLUE Crafted from ceramic, the sleek Summer Blue dial features a laser engraved wave pattern, raised indexes filled with unique light blue Super-LumiNova, and re-shaped rhodium-plated skeleton hands. Mirroring the tones of the dial, the blue ceramic bezel features a summer blue enamel diving scale, while on the reverse, the case back features a stamped, commemorative Seamaster logo. The helium escape valve has always been a key feature of the 300m collection - this new model features a conical valve with ingenious, patented technology that enables the watch to remain water resistant to 50 metres, even if the valve is accidentally opened while under the water. The 42mm stainless steel case fastens securely with a blue rubber strap.
