Hi-beat vs spring drive

I can tell you that I was in the exact same dilemma. I went back and forth between the SLGH005 and the SLGA009.  I want to point out I'm not opposed to Spring Drive, the technology behind it is absolutely amazing.  The new 9RA2 having 120 hours and the PR status on the back are all great points. But comparing that to the 9SA5 with the  Dual Impulse Escapement, I decided I ultimately wanted a fully mechanical movement and additionally I found the 9SA5 much more appealing visually so ended up going with the SLGH005. I’ve had it now for about 6 months and absolutely love it.

I've been leaning more towards the fully mechanical but the smooth sweeping seconds hand is just so spectacular to look at, but knowing its pretty much a hybrid between quartz and mechanical sort of takes away from the movement in a way. I appreciate the comment👍👍

Spring drive, as I must say I love the tri-synchro regulator and the dual escapement on the mechanical movement 👍solid watch from grand seiko there

The dials are not the same. The spring drive’s is a little whiter and the hi beat’s is a little more silvery. I think it has to do with a difference in dial texture. If that matters, make sure to see them together side by side. The difference is subtle but unmistakeable. It cemented my decision to go with the spring drive.

I thought the difference was the depth of texture(just a guess) thank you for I forming me!

Exactly. I edited my comment before you left this reply. The difference in color is likely owing to a textural difference.

I love how confusing this is, I think grand seiko dials are unmatched in quality and the inspiration, shows intricate the design really is, thanks for your help:)

This my friend is the definition of a 'Champagne Problem'!

😂I should bet my life savings on a game of roulette and buy both, no more dilemmas then 😭

I don't currently have a Grand Seiko in my collection, but the primary reason I'd have for adding one would be for the smooth sweep of the spring drive. The finishing and the dials are certainly part of the appeal as well, but without spring drive, to me they're just another nice watch.

I own both and feel they are equally valuable. I do appreciate the accuracy of Spring Drive for daily wear.

I voted Hi-beat specifically for the 9SA5. The technology and finishing is insane for the price. Also GS has a long history of Hi-beat movements so that interests me. Spring Drive is an innovation and I love the smooth sweep. But I could stare at the 9SA5 all day!

You can't compare Apples to Oranges. Both ate stratospherical movements! 🍏🍊

I have a hi beat soko frost and will also get a different spring drive. Can’t miss with GS.

I wouldn’t get a GS mechanical watch. I would either go straight to Spring Drive or as alternative go quartz.

I own both and they are both best in class. Spring Drive being in a class of its own there really isn't a bad choice.

The spring drive version barely has any texture to it. It’s a very flat dial that’s almost white. The only depth on the spring drive are those little groves and it’s dramatically different from the SLGH005. The hi-beat version is much more texturized, and has a silvery, almost glittering shimmer to it. I much prefer the SLGH005 Hi-Beat aesthetically. I’ve always found the spring drive variant to be extremely underwhelming compared to the best of GS. The only downside to the caliber 9SA5 is their teething issues with regulating them. Mine and many other owners have had to send them in for a proper regulation due to them running way too fast. Mine ran +11 to +13 seconds a day out of the box and never improved. That was very disappointing for a watch in its price category and with such new technolgical innovations.

I have a spring drive (not the new one, just the standard) and a hi-beat (the new 9SA5). If you want a gorgeous movement and purely mechanical watch get the hi-beat. If you want a precision time piece that will amaze you with it’s accuracy and entrance you with its mesmerizing seconds hand, get the spring drive.

If I could only have one I would get the spring drive, hands down. To me it’s a huge part of what makes Grand Seiko Grand Seiko.

All that said, of the two “white birches” I think the move silver-ish dial on the hi-beat is just stunning.

These are the pros for each for me personally

Spring drive:

Smooth seconds hand movement.

Accuracy in timekeeping.

Longer power reserve.

Hi beat:

Better looking movement. 9SA5 looks beautiful compared to the 9RA2.

The dial on the hibeat white birch looks better than spring drive version. The grooves look deeper and more pronounced on the hibeat version.

Servicing a high beat movement may be easier compared to spring drive

Spring drive have longer service interval about 10yrs

Hi-beat about 3-5 yrs

Spring drive on 90% identical to mechanic watch, the differences only in escape part.

I opted for the High Beat have yet to purchase a spring drive, Grand Seiko is forever innovating so I intend to buy one that convinces me fully that I will not debate my choice. My HB White Birch is my 3rd GS so it is finally time for a SD.
