Seiko

I thought you guys would want to be aware of an annoying issue with the 9SC5 caliber, just in case any of you are considering a Grand Seiko Tentagraph as a year-end holiday gift for yourself. When I inquired with GS, they formally advised me that they nei...  

Im a huge fan of Grand Seiko and was similarly excited for their 9SA5 movement. Technically very impressive but the fact of the matter is it simply doesn’t keep time well and in the beginning many left the factor with issues running at 20+ per day. Their ... 

I truly get the feeling that GS has been rushing their new movement intros (including the 9SA5 in the Birch models) without first resolving their teething issues. I tried the chronograph function on all of the brand-new Tentagraphs in stock at one AD and,... 

I know of some Birches that needed a spa treatment to ensure accuracy. In GSs Defence this was done without fuss, free of charge and fast.

but I've given it a pass, since I usually rotate watches often anyway.

"When everyone experiences the same software bug it becomes a feature."

I'm going to recycle that when explaining my personal bugs to the mrs.

I read that it would need to go back to Japan for any servicing. I don't think the Tentagraph is an integrated chrono.

In fairness to GS, I perhaps add that I've not had any issues with any of their earlier calibers (whether automatic, hand-wound, or Spring Drive).

I have had several rare GS models go back and it's not been a problem... Perhaps it was the attitude not the mechanism?

but several of the ADs (excluding the one where I got my Tenta, who was non-committal) whom I initially consulted said the modular aspect should not be a factor in perturbing the running-seconds hand.

It would most likely not have ended up under the tree (unless Santa was to include a heftier left wrist in addition) but good to know. Don’t remember this from the 8R48 movement…

I can vouch for the proper functioning of the 8R46 movement in my Speedtimer line as well.

I also noticed another issue linked to the chronograph function on an older blue dial Tentagraph at a local AD. Not sure if GS has addressed it in later releases. Basically; while doing continuous start/stop (without resetting) action on chrono, I noticed...
