The brushed finishing of the case is accented with polishing only on the teeth of the bezel and the edge of the crown. Accordingly, the watch sits larger on the wrist, measuring 42.7 mm in diameter, though at the same height as the previous model at 13.2 mm. Turning to the SPB237, we see a rounder overall design, this one drawing its influence from the вЂњTunaвЂќ styles first developed in the 1970s by Seiko. Beating steadily at 21,600 vph, the movement is protected behind a solid caseback, which helps provide the watch with an appropriate 200-meter water resistance. Inside the SPB239 is the Seiko Caliber 6R35, an automatic movement with a 70-hour power reserve, making it well equipped for casual wear during the week. Sweeping over it all are two large, lume-filled hands for the hour and minutes and a rectangular-tipped pointer for the seconds. The dialвЂ™s sunray textured surface is outlined with a simple outer minute ring and has applied, lume-filled markers at each hour position except at 3 oвЂ™clock, where a contrasting date window is found.

Over the top of the case is a unidirectional bezel with a prominent 60-minute diving scale in the same colorway as the dial. The lugs of the watch are quite blocky - a signature of the vintage model - helping keep the overall look very sleek. The watch uses a 40.5-mm by 13.2-mm steel case, with primarily brushed finishing and polished accents on its sharp edges. This material also offers greater resistance to degradation via water and sunlight.ДЇocusing first on the SPB239, we find a familiar, vintage 62MAS-inspired dial design distinguished by a black and faux-patina colorway. The straps use a traditional braiding technique from Japan called вЂњSeichu,вЂќ which according to the brand provides them with a tensile strength four times stronger than that of previous fabrics used in its watches. Most notable about this pair of new releases is their shared use of a new water-resistant fabric strap (above). The watches follow up on the 55 th anniversary quartet of releases launched in 2020, two of which also recalled the historical watches referenced here. Like many previous watches that Seiko has produced in a neo-vintage style, both of these new models channel many of the signature historical attributes of their historical predecessors while adding upgraded materials, finishing, and colorways, as well as slight adjustments to their silhouettes. The dual release includes the SPB239, which is a re-interpretation of SeikoвЂ™s first dive watch from 1965 (aka the 62MAS), and the SPB237, which a revamp of another noteworthy Seiko diver from the 1970s. Recently, Seiko once again revisited its archives to introduce two new vintage-inspired divers. With a vast catalog of offerings at many different price points and levels of precision, the Japanese brand excels in producing watches that appeal to a wide variety of enthusiasts. Few dive watches, historical or modern, enjoy such persistent praise from knowledgeable aficionados as those produced by Seiko.
