![]() ![]() The lugs feature a very organic and subtle curve that only just begins to dips healthily below the actual caseback. Also, projected battery life of the Grand Seiko 9F82 is 3 years. There are many other reasons to love the 9F quartz movement, so I encourage you to check out Grand Seiko’s page on it. By scaling back the minute hand advance from crown turning, you can hone in on the exactly minute markers you want to with steadiness. This is in contrast where other quartz watches allow a full rotation to advance the entirety of the dial at 60 min. Hyper time adjustment precisionĪs if everything else this movement does isn't enough, the 9F quartz empowers you to keep your watch as precise as possible by allowing a full rotation of the crown to only advance the minute hand 20 minute. Due to the "Backlash Auto-Adjust Mechanism," which is essentially a hairspring that affords enough resistance against the counter-bounce of the second hand to stabilize it as it ticks forward. You ever see on a quartz watch how the second hand bounces when it ticks? The Grand Seiko 9F quartz movement doesn't do that. ![]() This helps keep the intricate parts of the watch clean while also sealing in the vital lubrication to keep the interior moving components healthy and friction-free Second hand backlash compensationĪlright, this one is frivolous but still badass. Oh yea, the critical components of the movement are sealed in dust-proof enclosures. The sealed quartz movement features a regulation switch, allowing service techs to tweak the mechanism to maintain the quartz movement's high accuracy. ![]() The Seiko 9F quartz is one of the exceptions to this situation. Most quartz watches can't be regulated due to the simplicity of their construction and the nature of their longevity. ![]() Mechanical watches can be regulated and adjusted to compensate if they start to beat too fast or too slow. So what actually makes the 9F quartz movement in my SBGV233 special? Here’s some insight: The quartz movement can be regulated The updated version of this movement is the 9F85 and is basically the same but features an independently moving hour hand.Īccuracy on this Grand Seiko quartz is +/- 10 seconds per year, meaning its basically the most accurate thing in my house next to my cell phone (which doesn’t count). My Grand Seiko SBGV233 features an older 9F82 quartz model (3 hander). That said, the in-house 9F quartz calibers from Grand Seiko are easily in the top 3 FINEST quartz movements in watchmaking production today (for those curious, I’d throw the Citizen Chronomaster Quartz Movements and the Breitling Thermocompensated SuperQuartz movements into that mix as well). The choice between a quartz movement or a mechanical movement should have nothing to do with how much you want to prove to someone else how into horology you are. Quartz watch snobbery is never going away – we’re always going to hear crap like “Mechanical movements just feel more real.” There are good mechanical movements and bad mechanical movements – just like there are good quartz movements and bad quartz movements. Eventually I realized that the 9F quartz movement was for me. Then I toyed with the notion of a mechanical watch (or a GMT). Originally I wanted a Grand Seiko Spring Drive. You’re damn right this is a quartz watch and I’m starting my review with that fact because the quartz movement is the reason I wanted a Grand Seiko. Isn’t it totally unfair to think of every watch until your grail as a throwaway purchase?įinally being in a position to get this Grand Seiko grail allowed me to really take a look back on how my collector’s journey has progressed and to maybe try to get insight on how I want the future of how I collect to look. It’s a sentiment I’ve shared on the show, contradicted, then re-validated, then probably contradicted again – if that doesn’t emphasize my struggle with this concept I don’t know what will. From the very first day I learned about Grand Seiko watches, I was obsessed with this notion that every watch I ever got was only ever leading to me getting a GS. ![]()
