New $1,350 Seiko Diver is +12 per day!! Options

Option 5: wear watch. Enjoy. Reset once a week (if you are wearing it every day), or as needed.

You will be more mad if you damage the caseback or movement with your tinkering. The watch is in spec. Enjoy it for what it is. I have a large collection and need to wind/reset my watch almost every time I put one on… it’s a non issue. Take the 30 seconds to set or reset the watch. Might be good for you.

If I reset the watch constantly, it will wear out the thread in the crown and tube. Then I will have to take the watch in to get it serviced.

The 6R35 is a high quality movement and is capable of +/-5 seconds a day with a minor adjustment.

The fact is Seiko unfortunately in an attempt to save cost and lower the price point substantially broaden the accuracy specification to +25 to -15 seconds per day. That is not a specification on the basis of capability but on the basis of monetary considerations.

If a Seiko has the capability of being as accurate as a Swiss watch then I want to have that capability utilised.

It's like a car that is detuned to comply with regulatory requirements, but which is capable of much greater performance if tuned to its full potential.

No you won’t. Seikos are designed to be used. Don’t be afraid to operate the watch.

By the way, you are talking about a potential future service (which is baloney), vs a definite service or regulation now. Think about that.

If you know what you are doing, I’d say go ahead and regulate it yourself… but based on this thread I’m, um, skeptical. You are opening a can of worms for no reason. Recipe for dissatisfaction. Let us know how it goes.

I agree it can be done, but I question whether it’s worth the hassle / risk.

3.
Did it for the exact same movement. Easy

I've regulated a few Seiko automatics without a timegrapher but it took lots of patience and a little luck to get them set. Certainly doable.

Wait a couple of weeks before regulating it, otherwise you might have to do it again. I have a 6R35 watch and it started at about +10s/d but settled later to just a couple seconds fast a day.

If I scratch my caseback I'm going to scream.
Looks like I will need to buy a caseback opener. Hopefully Seiko service centre will just loosen my caseback a little to make removal easier for me.
Then I'm not sure if I need a de-magnetiser as well.
I'm going to use a wooden toothpick or skewer to adjust the beat rate and speed.

Keep us posted. It will be interesting to get your take on the process and the outcome of your efforts.

I have two Seiko watches with the very similar 6R15 movement. Bought a timegrapher, magnification/illumination glasses, case holder, and a case opener. I experimented on a 4R15 movement, a lot. Eventually, I ruined it after obtaining pretty good accuracy. Too bad; it was a "Spork", a watch somewhat sought after these days. But I persevered; my steady hands (and pure heart;) have the SBDC051 running +2 sec/day consistently; the 053 runs -2 sec/day. I can live with that.

You might want to get an SKX or cheap Turtle to practice on; those movements are easily obtained and replaced if you goof up on the first go-around.

Hey Steve. I bought the SPB151 yesterday. I think you are right about the black dial vs the blue. I am waiting for it to arrive from Japan, so I should get it mid June. I'm interested in your self regulation of the watch. I'm curious to see how much daily deviation mine will have. I'll be checking this thread from time to time to see how you make out with the process. Good luck with it, bud.

I’m glad you chose option #3!

Just put a poly bag over the case back before opening it. It not only protects the case back from scratches, it also gives the opener a better grip.

Also, correct the beat error first, before regulating the timekeeping.

Have fun!
