50 years… 50 years of advancement, 50 years making expertly arranged watches, 50 years of inundation in the chilly oceans all around the planet – or essentially being tied on the wrist of watch enthusiasts. From the principal utilization of a titanium case for a jumper’s watch to the creation of the accordion-style tie and the two-layer case to the plan of dial markers and hands of unmatched readability, Seiko had been engaged with improving instrument watches made to plunge for a very long time. To praise this commemoration, Seiko is coming with two extraordinary watches. One of them is an extraordinary accolade for the MarineMaster arrangement. Here is the Seiko Marinemaster 1000m a.k.a Emperor Tuna Rose Gold ref. SBDX014.
A quick view on 50 years of plunge watches by Seiko
Back in 1965, Seiko presented their first expert jump watch, the prestige 6217, with a pivoting bezel and a 150m water-obstruction (more to find out about it here , here and here ). From here on out, a piece of the assortment was work with the solitary aim to lure proficient jumpers and to satisfy their necessities with purposely assemble watches. PROSPEX watches are not to be mistaken for Seiko’s standard mechanical line-up of watches. The form nature of these watches are a long way from modest and Seiko’s PROSPEX is likewise one of the main trend-setters as far as jump watch advancement.
In 1975 Seiko uncovered the Professional 600m diver’s watch (6159-022). This is a significant watch as it was the first diver’s watch to be made in titanium – a material that was pretty much saved for models or NASA watches around then, yet a material with a lower thickness and an incredible protection from erosion. It was additionally the principal Seiko (and the main watch) to come with accordion-style lash – made on the grounds that at high-pressures, the diving suits will in general therapist, so the rubber strap can be worn firmly to compensate for this reality. This anti-attractive, exceptionally shockproof, and profoundly radiant watch was additionally coming with another approach to develop cases: the two-layer case. Ensured around by an outside black coated titanium case, the fundamental part is made of a single bloc that is first profoundly waterproof (water impervious to 600m) yet in addition a structure effectively impermeable to helium, thus eliminating the requirement for a helium valve. The watch could then be securely utilized for immersion jumping to incredible depths.
the 2015 Seiko Marinemaster 1000m Emperor Tuna ref. SBDX014
This new 2015 Marinemaster 1000m Emperor Tuna is an unadulterated accolade for this 1975 Titanium 6159-022, as it comes with large numbers of the ascribes of this vintage release. It is difficult to trust it, however indeed, the 2015 release is somewhat of a re-issue that is both outwardly and in fact near the vintage one. Seiko is typically not into this sort of ‘marketing stuffs‘ but rather bad-to-the-bone gatherers and devotees will absolutely be satisfied to see a particularly unwavering watch. The new Emperor Tuna depends on a similar engineering, same case development, same expert norms – the interior PROSPEX & the ISO 6425 affirmation that Seiko assisted with making (more about it here & here ) – with anyway refreshed highlights and present day clues.
The 48.2mm case depends on the two-layers development, however here with present day materials. The internal case is as yet made of titanium – for the reasons we uncovered before – but with rose-gold tone and dark hard covering. The case is additionally as yet depending on the one-piece/monobloc case structure, implying that there is no screwed caseback. The development is cased from the top, before the dial and the precious stone – much the same as the principal releases of the Omega Seamaster Ploprof . This permits the watch to be currently water impervious to 1.000m (indeed, it arrived at 3.000m attached to the outside structure of KAIKO 7000 II, a distantly worked undersea exploration vehicle) and to be fully impermeable to helium – motivation behind why there is no helium valve like in an Omega Seamaster Planet Ocean or a Rolex Sea-Dweller 4000 .
The external shell – what authorities called the shroud – is currently made of exceptionally safe dark earthenware. This external shell is made both to secure the case if there should arise an occurrence of stuns and to prevent any inadvertent turn of the bezel. Discussing the bezel, other than being covered with rose gold, it comes with the typical plunge watch configuration, which means a unidirectional revolution limit and an enormous, decipherable hour long scale to be utilized to compute decompression times. The dial is additionally dedicated to the first – and subsequently very commonsense and clear – as it comes with enormous radiant spots, implement and three-sided lists – to be effectively readable and unmistakable even in obscurity – and huge glowing hands. Both the hands and the files are coated with a warm velvety shading that coordinates the possibility of a vintage re-issue and that consummately blends in with the overlaid bezel. It comes with a circumspect date include situated at 4:30 with white numerals imprinted on a dark disc.
Inside the 2015 Seiko Marinemaster 1000m Emperor Tuna Rose Gold ticks one of the center reach self-winding developments – the top of the line one are those made for Grand-Seiko or the ones with high-beat include. The Calibre 8L35 is a cutting edge development that, as common with Seiko, is created, planned, produced and amassed completely in-house, at the Shizuku-ishi Watch Studio. It probably won’t be done with haute-horlogerie norms (don’t expect cleaned inclined points or Geneva Stripes, we’re talking instrument watches here), it is anyway a dependable and proficient development that demonstrate its characteristics. It ticks at 28.800vph/4Hz, has 26 gems and flaunts roughly 50 hours of force save. This programmed type 8L35 is managed to an average +15/ – 10 seconds for each day.
On the wrist, the Seiko Marinemaster 1000m Emperor Tuna Rose Gold is a huge, enormous watch (recall that the case measures 48.2mm x 17.4mm). In any case, because of the elastic tie and the shortfall of hauls (the tie is appended under the situation), it is a significant simple watch one the wrist. Other than that, this size and this remarkable shape are important for the inclination and devoted to famous watches it honors, including the 1975 ref. 6159-022. Price in Europe: 3.450 Euros.
