To the casual watch-wearer, Seiko is just one brand of high-quality watches but those who spent some time winding crowns will take pleasure embracing its higher-end sub-brands, not all of which are readily available always. The Prospex (Marinemaster) comes under this category second only to the Grand Seiko, and way ahead the Seiko 5 models. In fact, this is one watch that can give a lot of Swiss-made watches a run for their money, especially in the finish, specs and quality departments.
A very well made, functional model with a robust nature and busy looks as opposed to the currently prevailing bling factors; this is simply quality workmanship as expected from Seiko. But, that’s only for him already enamored with the Divers and fascinated by chrono-s; else, welcome to this small and select group who will prefer it to be the everyday work & play watch unless you have grayed from the insides.
The Seiko Prospex collection is homegrown chiefly for the Japanese consumers in the domestic market; especially for them finding scuba diving a great sport. The quartz Cal. 7C46 movement of the SBBN017 Marine Master doesn’t waver for more than 15 seconds a month and runs approximately for 5 years on a new battery. There’s a battery charge indicator to lighten your troubles a bit. But the real deal is the stainless steel casing utilizing a special L-shaped gasket to make it anti-magnetic. For maximum visibility, Seiko’s own non-radioactive LumiBrite technology helps store light for 5 hours against a 10 minutes charging. Besides, it is also 30ATM WR and safe for 1000-feet down under.
It is unbelievable value from a very functional watch made by professionals for the professionals, so that tasting the salty waters leave a sweet taste to the mouth. It also withstands mixed-gas use – no, not with helium escape valves but stopping helium particles from entering the watch case only.
