When the SPB077 had a 44mm x 13.1mm case, these new models are 42mm in diameter with a height of 12.5mm. So here we are, face to dial with these new SPB185J1 and SPB187J1 and the first thing to note is indeed the “downsizing” effect. It indeed already featured all elements that made modern Seiko diving instruments easily recognizable – the angular lugs, the crown at 4 o’clock, the typical applied indexes and hands While not the very first dive watch of the brand (that the 62MAS), the 6159-7001 could be considered as the one that laid the foundation for the brand’s design codes, which are still in use today. The 1968 diver has recently been a major source of inspiration for Seiko. The retail is $700 on a calfskin leather strap (SPB157 and SPB159) and $725 on a stainless steel bracelet (SPB155).Seiko Prospex 2020 Vintage 1968 Reinterpretation Diver's Watch

And lastly, the date window is not magnified whereas those with the compass have a cyclops lens over the date aperture.Īs mentioned above, both styles share Seiko’s upgraded modern caliber 6R35 3Hz automatic movement, which has 24 jewels, 70-hours of power reserve, plus manual winding, and stop seconds.Īll six of the 2020 Prospex Alpinist timepieces feature a sapphire crystal protecting the front, a screw-in exhibition caseback, a screw-down crown, and 200 meters of water-resistance. One of the biggest variations between the two is that the hour markers are applied on the compass equipped models and printed on these new gradients dials. And the finish of the dials is textured (knock-down) versus smooth sun-ray finishing on the three Alpinists watches with compass bezels.Īdditionally, the smaller, less complicated Alpinist references share the same prominent, skeletonized, luminescent cathedral hour and minute hands, and baton seconds hand (red-tipped on these new references), and generally the same look with the exception of different chapter rings. For these new models, the dials a graduated, with lighter hues in the middle that are darker towards the peripheral. The aforementioned models we initially covered, with the rotating bezel, allowing you to more easily visualize all the directions, but either watch uses the same principle.įurther differentiating the two sets of Alpinists wristwatches are the dials. Plus, like with most standard watches, you’re still able to hold the watch horizontal, with the hour hand aimed at the sun, and then halfway between the hour hand and 12 o’clock is your due south bearing, which allows you to then determine all four cardinal compass points. While you’re losing the awesome inner bezel compass with these minimalist Prospex Alpinist references, you’re also trading that for a marginal size reduction which means the watches will better fit smaller wrist sizes. Both styles measure the same 46.4 mm lug-to-lug. By comparison, the three new Prospex Alpinist references (SPB155 -green, SPB157 – blue, SPB159 – black), are housed in slightly smaller cases measuring 38 mm x 12.9 mm. Those three references (SPB121 – green, SPB119 – cream, SPB117 – black) come in stainless steel cases measuring 39.5 mm x 13.2 mm and share the exact same caliber 6R35 movement. We previously wrote about the 2020 Prospex Alpinist models, that most notably feature a rotating inner bezel with a 360-degree compass scaled printed on the flange, controlled by a second crown located at 4 o’clock. Seiko introduced two new Alpinist model lines this year, both inspired by past designs, and equipped with modern Japanese mechanical movements. The Seiko Prospex Alpinist collection was inspired by the company’s 1959 watch collection by the same name, which is considered Seiko’s first sports watch.
