Introducing The Seiko Prospex SPB143, SPB145, SPB147, And SPB149 Interpretations Of Seiko’s First Diver

Brisk Take

Sometimes I compose something pointed here – something that, in my psyche, functions as a joke, or a piece of commentary, or something to get you intrigued. Not today. Today, I don’t have to come up with anything, in light of the fact that Seiko has recently reported an update to their 62MAS-propelled Prospex SPB line of 200m plunge watches. Every one of the four of the new models have 40.5mm-wide steel cases and a value point that is a negligible part of that set up by the genuinely flawless SLA017.

Introductory Thoughts

Allow me to offer some setting trying to adjust my energy. At Baselworld 2017, Seiko reported such a re-issue of their first plunge watch, the profoundly collectible 6217-8001 otherwise known as the “62MAS.” The new model, the SLA017, was essentially an ideal articulation of a Seiko jump watch. Estimating in at 39.9mm with a steel case, the SLA017 was restricted to 2,000 pieces, shaken a top of the line 8L35 development, and retailed for $3,400. The SLA017 dispatched close by two more open articulations of a freely comparable plan (the watchword here is “freely”). And keeping in mind that these two models, the SPB051 and SPB053, are actually very decent, they are likewise bigger at 42.6mm and didn’t figure out how to catch a similar charm (though even at a more financial plan amicable level) as that of the SLA017.

This carries me to a group of four of pristine SPB jumpers, the 143, 145, 147, and 149. Presently estimated at a not-common-to-Seiko 40.5mm (likewise 13.2mm thick, and 47.6mm drag to haul), these new models additionally offer a dial plan that is a whole lot nearer to that of the SLA017 and its beloved daddy, the 62MAS.

Starting at $1,000, the SPB147 comes on a dark silicone tie and has an earthy colored/bronze dial with plated highlights that reach out to the bezel. The $1,200 SPB143 has a dim/dark dial and a standard bezel execution coordinated by a three-connect style steel wristband. Additionally at $1,200, we discover the SPB145 which is a Seiko store release with a unique caseback and an earthy colored/dark tone bezel. At last, there is the $1,350 SPB149, which has a blue dial with yellow/gold accents (hard to tell from the press images); it comes with both the arm band and a blue silicone tie and is restricted to 5,500 pieces.

All variants, paying little heed to reference, sport 40.5mm wide steel cases that have Seiko “overly hard covering” alongside 200-meters water obstruction, a twofold domed and hostile to intelligent sapphire gem, and Seiko’s LumiBrite lume. Timekeeping is overseen by the Seiko 6R35 programmed, which ticks at 21,600 vph and offers hacking, hand-winding, and a force hold of 70 hours. At the cost point, these are strong specs and, talking by and by, I’m so eager to consider these to be individual as that 62MAS and its skin jumper esque case is so acceptable on the wrist (and remember that the SLA017 estimated ~46mm drag to lug). On paper, these new models look ridiculously promising. 

To my eyes, this is a colossal delivery for the sub-extravagance commercial center. A pleasantly measured and totally skilled Seiko jumper that catches one of their best jumper plans while guaranteeing legitimate specs, a strong and solid development, and a value point that is short of what 33% of that set up by the – in fact higher-spec –  SLA017. Following the dispatch of the SPB151 and SPB153 “Chief Willard” jumpers (which are additionally somewhat engaging at 42.7mm), these new Prospex SPB14X models feel bound for any wrist searching for that center Seiko advance in a marginally more modest, somewhat more cleaned execution. I can hardly wait to see these in the metal.
