5.0 out of 5 stars The 'BFK' - a solid workhorse of a dive watch., 15 Aug. 2012
Verified Purchase(What is this?)
This review is from: Seiko Gents Kinetic Divers Watch (Watch)
I've owned many watches, some expensive, some cheap, and in my work and hobbies I use them in harsh salt-water environments. The Seiko kinetic ska-371 (nicknamed the "BFK" or Big F*** Kinetic by watch aficionados) is a well liked, robust dive watch that can take a beating and still deliver. It's not perfect - I wish Seiko would use sapphire crystals instead of the easier to scratch 'Hardlex' glass - and the lugs should really be 22mm not 20mm, but at the price point it's one of the best-engineered watches out there.
The 5M62 kinetic movement uses a combination of good old-fashioned mechanical technology to generate the electricity that powers the quartz movement. Each time you move your arm a weighted rotor inside the watch turns and spins a micro-generator that trickle-charges a rechargeable battery.
The early kinetics from the 90's developed a bad reputation because they stored the energy in a capacitor, which usually failed after a few years so that the owner gained little advantage over choosing a normal battery-powered watch, as the kinetic needed an expensive service to restore to life. Thankfully Seiko have overcome those early difficulties and the movement inside the 'BFK' is reliable, accurate and robust, with up to 6 months power reserve once fully charged, though to achieve that you'd need to wear the watch most days.
The case of the watch is fairly heavy but is strong, and the 120-click bezel is raised above the crystal affording some protection from knocks. Luminosity is good enough to last the night, and the skeleton hands do the job, though they could do with silvered edges and a full coating of luminous material to be perfect. The bracelet is heavy and has good adjustability, and is easily removed via the drilled lugs if you prefer to fit a strap. All in all a good value watch than will last many years and can be used for real-world scuba diving if you wish.
