Seiko MarineMaster 300M SBDX001 Watch
A Watch with a Cult Following
More than simply a dive watch, Seiko’s Prospex Marinemaster 300 is a cult piece. It’s a modern spin-off of the company’s first dive watch, which was released exactly 50 years ago, in 1965, and it features the same retro look: black dial, large lumed hour markers, thick case, wide black bezel. But what’s truly unique about the MM300, as it’s known, is less visible.
Note: Since this is a Japanese domestic market model, the manufacturer warranty is only valid is Japan. This watch is covered under a Massdrop 2-year warranty. These watches will be shipped from the US. This drop is limited to 12 units.
Seiko 8L35 Movement, Monoblock Case Construction
For one, it’s equipped with Seiko 8L35 automatic 26-jewel movement, beating at 28,800 beats per hour. It also features a 50-hour power reserve, which allows it to remain accurate even when it’s been idle for more than 2 days. Milled from a solid block of 316L stainless steel, the monocoque case is also different from most watches. Combined with the screw-down crown and the dual-curved Hardlex crystal, it’s no wonder the MM300 has garnered a following among divers and watch enthusiasts alike.
