Seiko Marinemaster 300
This article examines the Seiko Marinemaster 300, a dive watch praised for its quality and unique features, questioning its value proposition in the current market. It highlights the watch's monobloc case construction, Zaratsu polishing, and the robust 8L35 movement, comparing older models like the SBDX001 and SBDX017 with newer iterations.
- Monobloc case construction
- 8L35 movement based on Grand Seiko 9S55
- SBDX001 retailed around €2,000 in 2014
- SBDX017 features (Diashield) coating
- Current Marinemaster HBF001 retails for €3,800
The monobloc case construction means all servicing is done from the front, eliminating a case back and enhancing water resistance, particularly for saturation diving.
The case finishing, including sharp polished surfaces and Zaratsu polishing, is noted as being on a different level compared to other Seiko models like the Sumo.
The 8L35 movement is derived from the Grand Seiko 9S55 caliber, indicating a high level of engineering and finishing.
The SBDX017 introduced a Diashield coating for increased scratch resistance, though the author preferred the original SBDX001.
The watch's dimensions, while large, are considered manageable and contribute to its GADA (Go Anywhere, Do Anything) potential.
The bracelet's clasp extension mechanism is described as potentially cheap-looking and prone to accidental extension, though functional when worn.
Newer Marinemaster 300 models (HBF001) retail for €3,800 and feature technical updates like a ceramic bezel and 8L45 movement, but lack the monobloc case.
