One of the most iconic dive pieces from Seiko, which has strictly been sold in the Japanese market , is the Prospex Marine Master Professional “Tuna Can”. The nickname Tuna Can basically describes how the piece looks on the wrist. Like a big can of tuna, which is only fitting for this dive piece. I know, for many years, people have waited to see if the watch would ever be available with the unique Spring Drive movement. Earlier this year, rumors started spreading and now the hope of seeing the infamous Tuna Can with a Spring Drive movement has become a reality in a limited edition of only 300 pieces for the world.
The 1st time Seiko introduced the shrouded “Tuna” case design was in 1975. The titanium shroud provided an airtight, watertight, corrosion and abrasion resistance with over 20 patents in the exterior alone. This 600m divers piece became iconic and was one of the best dive tools on the market back then. Today, with an even more elaborate case design, the new Spring Drive Tuna will make for one of the most accurate, mechanically driven 600m dive watches on the market.
There are many factors making this timepiece such an impressive dive tool. Its DLC coated titanium structure that protects the watch from impact and shock and also ensures its security in extreme conditions. The torque control unidirectional rotating bezel has excellent functionality, operating smooth but solid and can easily be grasped on the openings from 12:00-3:00 and 6:00-9:00, providing even more added security so the bezel does not move accidentally. Another factor is the “L” shaped packing structure utilized to provide complete air and water tightness at one of the highest standards across the globe. The polyurethane strap has a great level of elasticity, perfect for the varying change in water pressures. Finally, the crown located at 4:00 to provide comfort to the wearer as well as keeping it safe from potentially catching on something. Of course, the Lumibrite applied is incredibly strong, helping visibility in darkest of waters.
The new Seiko Prospex Tuna Can Limited Edition SBDB008 just had its official press release by Seiko Japan and is anticipated for delivery in the US sometime in early September (possibly earlier). The large case size measures out at about 50mm wide, 16.2mm thick, and weighs in at 118g. The SBDB008 utilizes the 5R65 Spring Drive movement, and (as I mentioned) will be limited to only 300 pieces for the world. As we understand it, this may be one of the last Spring Drive models you will see outside of the Grand Seiko brand. Unfortunately, the entire Prospex series is still not available outside of Japan. This small taste, however, is the best piece you could ask for!
This piece has been wildly popular at AZ Fine Time, and with small quantities coming in, is already near sold out.
