Seiko is renowned for creating exquisitely-crafted diving watches that fit everybody’s lifestyle, especially the adventurers, professionals, watch aficionados, sports enthusiasts, collectors, and everyone in between.
To commemorate their 55 years of exquisite workmanship and unprecedented creations, Seiko is giving a new face to their first ever Tuna diving watch in mechanical form (62MAS) that was released in 1965 which then became a global standard.
With its highly impressive and unbeatable 1000m water resistance and the incorporation of Seiko’s new alloy they call as “Ever Brilliant Steel”, the new Emperor Tuna SBDX035 is pure grail and is considered the pinnacle of Seiko’s marine engineering and watchmaking.
The Fateful Letter
Seiko was the first ever to release a diving watch in Japan and their desire to improve their creations snowballed through a diver’s fateful letter. He expounded how all their watches got damaged in the depths greater than 300 meters while using a diving capsule and wished he could use something that can endure deep-sea diving.
This concern laid the groundwork and fueled Seiko to innovate and create more revolutionary watches that can withstand hardcore underwater activities.
The Reign of Emperor Tuna SBDX035
Seiko Prospex Automatic Professional 1000M Diver 55th Anniversary Tuna SBDX035 is faithful to its original design as part of Seiko’s preference to stick with the Tuna aesthetic. 
It means a lot for most watch enthusiasts to be able to witness something similar to the ‘60s to ‘70s models that capture the spirit of the brand that people fell in love with in the first place.
Since this is a reissue model of the original Seiko Diver, it keeps all the innovations that Seiko brought to diver’s watches in the 1970s such as the double layer construction with one piece inner case, the L-shaped gasket for helium resistance, and the accordion-style strap.
It has an automatic and manual winding mechanism and the ultimate choice for air diving with its 1000m saturation. Its case is made of anti-corrosive pure titanium with Ever-Brilliant Steel while its glass material is made of sapphire crystal.
There is LumiBrite on its hands, indexes, and bezel.
This legendary remake is a one-piece structure with a magnetic resistance of 40,000A/m. Just like most of their Tuna craft diver’s watches, it has a screw lock crown, 26 jewels, a black lid serial number, and a second hand stop mechanism.
Other features include a thick, toothed unidirectional 60-minute bezel in black and white accents, a perpetual calendar window, and hard black protective outer shell coating.
It is powered by Seiko’s automatic 8L35 caliber with a frequency of 28,800 vibrations per hour and stores 50-hour of power reserve.
This evolutionary piece is yet another iconic timepiece that absolutely keeps up with every diver’s adventurous lifestyle.
Emperor Tuna SBDX035 is only limited to 1,100 pieces.
Seiko Prospex challenges every limit. The design is undeniably impeccable, stylish, classic, rugged, yet absolutely luxurious both in style and functionality.
Emperor Tuna’s Precedents: SBDX011, SBDX013 & SLA042J1
Seiko has also released other re-creations for their 55th anniversary. They are Prospex MarineMaster Professional 1000m Diver “Emperor Darth Tuna” SBDX013, Seiko Prospex Emperor Tuna SBDX011 Marine Master, and Emperor Tuna Marinemaster 1000m SLA042J1.
These models also feature incredible upgrades and similar features as the SBDX035. They are all meant to withstand hardcore underwater activities such as deep-sea diving with their unsurpassable 3300 ft saturation.
