This material (nitride plated titanium) had a characteristic gold tint – a watch that Seiko aficionados named later the Golden Tuna. The titanium nitride coating and the characteristic golden coloration were changed by an all-black look from DLC-coated titanium (Diamond Like Coating). It’s not possible to discuss watches without the Rolex Submariner developing. SBBN013 – the Seiko Tuna, which we will assess in our forthcoming article. Because of its mechanical heart and limited production, this mannequin is extremely tough to search out and even costlier (and collectible) than the original 6159. Nine years later, the Japanese team determined to introduce an everyday manufacturing mechanical Tuna, the so-referred to as Emperor Tuna (the reference SBDX011). In parallel with the Golden Tuna lineage, Seiko paid tribute to the primary mechanical model produced in 1975. In 2000, Seiko produced in a limited version of 1,000 pieces, the ref.SBDX005, which shared the ethos of the iconic ref.
This model had a ceramic shroud, Hex screws, a different font, and eventually, a dial. The ref. SBBN011 – the Seiko Darth Tuna as called by followers – came available on the market later, and this time, it was a full stylistic overhaul. This massive 52mm x 17.4mm Marinemaster watch shares the styling clues of the Darth Tuna (all black, DLC-coated Titanium) and features the 8L35 caliber. Styling and materials used remained nevertheless precisely the same. It remained in manufacturing as much as this 12 months when Seiko revamped its entire line of its seiko submariner professional (Prospex) divers – introducing at the same time the Seiko Marinemaster 1000m Emperor Tuna Rose Gold SBDX014, for the 50th anniversary of dive watches by Seiko. 6159-7010. The Seiko SBDX005 Historical Assortment carries on the 6159-7010’s legacy, with the same manufacturing and design requirements, however, with an updated motion.
For many, the selection of a quartz movement is now considered a downgrade. The movement was also upgraded to the nice 7C46, with a 5-year battery change interval – a motion that remains to be used in precise Seiko Tunas. Unadjusted, however, is still a very nice piece of horology. One of the elegant Seiko 5 fashions is the Seiko 5 SNKK52. In early 1986, Seiko introduced the ref. Its successor was the ref. Can’t get sufficient of Seiko? You may even use dials from different watches within the Seiko lineup for an “OEM-Plus” look. Seiko’s so-called Turtle watches are highly acknowledged. The turtle uses Seiko’s 4R36 motion, which is exceptionally accurate.
