The long history of Japanese watch company Seiko could be traced back to 1881 with the opening of “K. Hattori”, a watch and jewelry shop in the heart of Tokyo by Kintaro Hattori. Three decades later, the founder decided to buy an abandoned factory and begin to manufacture the first wall clocks under the name of Seikosha which in Japanese terms Seiko has a meaning of “exquisite”, “minute”, or “success”, while Sha indicates “house”. As time went by, the brand also produced wristwatches and got highly respected from watch enthusiasts.

The very first generation started in 1959 where the Seiko dive watch only featured a manual winding and survived in 50 meter water depth. Six year later, they built a better performance with higher water resistance of 150 meters. Until now, this Japanese watch brand keeps producing and developing the best dive watches together with their best engineers.

What is a Dive Watch?

A dive watch is a watch that can withstand at least 10 bars of water pressure, is legible at a distance of 25 cm in the periods of dark, anti-magnetic, shock resistant, can hold out against saltwater, and provides diving time, for instance an unidirectional rotating bezel. With this helpful device, they can easily track the elapsed time and calculate decompression stops. And, Seiko has all of them.

Today, we will take you to the best Seiko dive watches in the series of 62MAS, Tuna, Marine Master, and others to see the greatest transformation Seiko’s ever made.
