Grand Seiko Introduces the Spring Drive 5 Days Caliber 9RA2 SJX Watches

Grand Seiko Introduces the Spring Drive 5 Days Caliber 9RA2

Having introduced a new design language along with the all-new, automatic 9SA5 last year, Grand Seiko is now doing the same for the Spring Drive. The watchmaker has debuted a pair of Heritage Collection Seiko 140th Anniversary Limited Editions, the “Minamo” SLGA007 in steel and the “Tree Rings” SLGA008 in rose gold. Both are powered by the 9RA2 that’s part of the family of latest-generation Spring Drive movements first seen last year in the Grand Seiko Diver 600 m SLGA001. Just 5 mm high, the slimness of the 9RA5 means the pair of new models are the thinnest Grand Seiko Spring Drive watches to date. Initial thoughts The new models are essentially Spring Drive versions of the self-winding Heritage models launched last year (including an ultra-luxe platinum version and the more recent “White Birch”). That’s a good thing for two reasons. One is the intrinsic appeal of the design, which is vintage inspired and appealing, packaged in a case that’s a good size and easily wearable. And the other is the increased consistency in styling between Grand Seiko’s Spring Drive and automatic models, doing away with the confusing distinction between movements and designs. The “Minamo” SLGA007 in steel But that’s also the downside for the buyers of the limited-edition models (either these or the automatics), since the design has been replicated as a standard-production watch with the automatic movement, and the same will surely be done for the new 9RA2 Spring Dr...

Ressence Debuts the Type 11, with the All New In-House RW-01 Movement Worn & Wound

Ressence Debuts the Type 11, with the All New In-House RW-01 Movement

For as long as we’ve talked about Ressence, part of the discussion has always been about how clever they are for producing such an ingenious and unique system for time telling, all built on top of a standard, off-the-shelf ETA movement. Their patented ROCS module, which displays the time via a series of rotating discs rather than traditional hands, is a complicated piece of engineering that has always lived alongside a caliber that is rather ordinary. For me, and many others, this was always part of the charm of a Ressence watch, and underscored the idea that watchmaking is a broad discipline and that with some creativity even a simple ETA movement can be turned into something extraordinary.  That changes a little today with the introduction of the Ressence Type 11, featuring the all new RW-01 movement, the first in-house designed Ressence movement. Designed specifically to power the ROCS, the RW-01 is an integrated, automatic caliber that appears to be an improvement in just about every way over previous movements found in Ressence watches.  First and perhaps most notably, this movement has a 60 hour power reserve, which can be monitored on the dial via ceramic micro balls. For years, Ressence watches have featured power reserves that topped out at slightly less than the ETA movements they were based on due to the demands of running the ROCS module. But the RW-01 was designed from the ground up to work with ROCS, eliminating many of the compromises made with previous ...

Grand Seiko’s Smallest High-End Quartz Models Yet

Grand Seiko has installed its high-end quartz calibre 9F in a 33 mm stainless steel case with fan-favourite textured dials, making one of the most advanced analogue quartz movements available in the smallest and slimmest format to date. The compact proportions of the Grand Seiko Heritage Collection Quartz 33mm “Snowflake” SBGX359 and “Skyflake” SBGX361 are possible thanks to a new member of the 9F family: the cal. 9F51. Though smaller, the new calibre retains all the technical bells and whistles of this class-leading quartz platform. Ref. SBGX359 (Snowflake). Initial thoughts While Grand Seiko’s quartz models are generally known as good value propositions, with the cal. 9F in particular representing a lot of movement for the money, that has generally been less true of the brand’s smaller models. These maintain the brand’s standout case and dial work but with relatively pedestrian cal. 4J movements. Though above average in terms of quality and technology, the cal. 4J lacks the torque necessary to accommodate the exceptionally large and refined hands found on most Grand Seikos. Ref. SBGX361 (Skyflake). Given the brand’s recent emphasis on Spring Drive technology, seemingly at the expense of battery-powered quartz movements, that seemed unlikely to change. In this context, this duo is a pleasant surprise, with more likely to follow, and offers a no-compromise Grand Seiko experience in a smaller size without the high price tags of the ladies automatic line. A ...

Seiko Introduces Prospex Alpinist GMT SPB493J Limited Edition Teddy Baldassarre

Seiko Introduces Prospex Alpinist GMT SPB493J Limited Edition

Seiko’s Alpinist collection is welcoming a new member this week with the release of a new GMT reference featuring a dial inspired by the hornbill, a tropical bird of Southeast Asia. The watch is a Land Alpinist using the brand’s 6R54 caliber, and while this is an existing configuration released back in 2023, there are a few unique details here worth noting - from dial textures and colors to the black bezel piece. This watch is not only a celebration of the majestic hornbill, but also an expansion of the Alpinist platform that goes beyond the existing framework, hopefully opening the door to more expressive variations moving ahead. The Alpinist GMT was released in 2023 in what felt like a very natural move for the collection. As part of the Prospex Land family, the new Alpinist references utilized a fixed, 24-hour steel bezel and an internally rotating compass bezel. Use of the 6R54 allowed the addition of a 24-hour hand into the mix; however this is the so-called “caller” style of GMT hand, meaning the hour hand cannot be set independently on the go. Still, it’s a welcome addition to the modern series carrying forth Seiko’s historic Alpinist name, and retains the charming design of the original. This newest reference to the collection is the SPB493J, and it mixes up the formula just enough to stand apart from the rest. This watch uses base blacks set against the steel 39.5mm case and bracelet, with the inclusion of a deep green color used for the rotating inn...
