Do your Seiko Automatics Run Fast?

[jasman]

I just got my second Seiko Automatic recently (this one is an SKX031 with a 7S26 movement) and observed it to run about +12 to 14 secs/day. This one appears to run similar to my earlier Seiko 5 military style watch, also using the same movement.

I heard that Seiko Autos always run fast. I just wondered what's the general consensus.

Also does anyone know the proper procedure to regulate the 7S26 movement?

My experience with any non-COSC watch is that it runs fast. I've had 4 Seiko divers and they all ran about +15 out of the box.

I've regulated 3 7S26 movements and they're a real PITA. Instead of a screwhead you turn to adjust it like the ETAs, there is a tab that you have to nudge with something like a toothpick. It usually takes 4-5 tries before you get it set. I got those 3 Seikos to +2 or better though. Same as the Miyota movement found in the Invictas.

I've had (and have) numerous Seiko Divers with movements ranging from the 6309, 7002, and the current 7S26 and they all run fast when new or recently serviced. Many run as fast as 30 sec/day but most I've had are in the 15-20 sec range. I've never regulated one since I wear so many watches that the error never builds up enough to bother me.

same her every automatic I ever owned and thats a LOT has ran fast the best out a the box I have ever had is a Bulova swiss made chrono with a 7750 movnt in it !! It was only about 3 sec fast from jump street and it was NOT COSC certified Iam still amazed at that watch....it has a Black face and a nice Brown croco on it its is my go to Black and tan I never pay much mind to how acurate a automatic is I set any watch when I put it on anyway .. with now my trusty tough solar atomic G shock ))I saw a couple a NICE citizens and a seiko today at sam's club.. I will NOT reveal how many watches I bought today if I did my wife might read this and I would be a dead man ))))))I Got her 1 thou lol

My Seiko 5 runs about +18 or so, not enough to un nerve me though as I don't wear it too much since I got my el cheapo Mido. but I think I will bust it open and try to regulate it some just to see if I can... ;D

I just checked my Seiko 5 last night and its at +7. I dont wear the same watch more than 1-2 days max so it doesnt bother me. It would only bother me if it was en expensive watch
