Let Me Expertly Repair Your Seiko Watch.
Vintage Seiko Watches to the Finest Seiko Watches of Today.

Why should you send your Seiko watch to us?
Seiko watch repair is what we specialize in. Over the past 10+ years we have performed thousands of Seiko repairs and service on both Seiko Quartz and Seiko Mechanical watches.
Seiko only repairs current model watches or those under warranty. Once the model has been discontinued they will service it for about 2 more years. After this time they sell off any remaining spare components to the supply houses. Once the components have been sold if you send your watch to Seiko for service they will tell you the components are not available any more. But in truth they just won't buy them back to repair your watch.
We don't play word games like that. No matter the age of your Seiko watch we will search high and low for the components to repair your watch. If someone has them somewhere on earth we will get them so that we can repair your watch and give it back to you working.
If the components to repair your watch are truely obsolete we'll tell you that. We don't make up excuses for not trying to find the components.
Please understand that sometimes on older Seiko watches although a supplier claims the component(s) are available they may not actually be available or it may take a length of time to get the them.
We had one supplier who told us a certain components for a very old Seiko watch was available and we ordered it. Our customer was very patient but after waiting several months he just wanted his watch back. So we sent it. The components did finally show up 1+ years later! It was on backorder with the supplier for so long they could not even tell us when we ordered it!
We have had other times when the components have taken several months to get here but these are exceptions and not the norm.

Seiko Mechanical Watch Repair
Mechanical watches have a lot of pressure that is applied by the mainspring to the tiny surfaces of the moving components. If you don't have your watch cleaned and oiled regularly dirt gets inside and mixes with the oil and acts like sandpaper. The oil also dries out and stops lubricating properly.
It is recommended that a mechanical watch be cleaned and oiled every 2-7 years depending on how well it is sealed. It's like the old Fram oil filter commercials - "You can pay me a little $, now. Or a lot $$$, later".
If your mechanical watch runs erratically or stops and starts after it is fully wound or doesn't keep good time it most likely needs to be cleaned and oiled.
Water and watches don't mix. Even the smallest amount of water inside a watch can cause major damage. If you see any sign of moisture or water inside the watch send it in immediately. Don't think it will just dry out and be fine. It will take a very long time to dry out and while it is drying out it will be causing rust and damage to the watch.
If your watch got wet or you see any sign of moisture or water inside the watch, send it in immediately. If your watch has gotten wet, even water resistant watches, and stops running, the problem more than likely is rust. It is very difficult to estimate rust damage and will be worked on at an hourly rate. The final cost depends on how bad the rust damage is. In some cases it may be less expensive to replace the movement.
I don't do swish and lube jobs. If you take your watch to a jewelry store chances are it is sent to a trade shop that does this type of job.
What I offer:
Each watch is disassembled and then ultrasonicaly cleaned, re-assembled, oiled and the movement is timed using a digital electronic timing machine. Then the watch is observed for 1-3 days to make sure it is operating properly. Prices quoted are labor only. Components, shipping and insurance are extra.
Seiko Mechanical Watch Overhaul Prices (Labor only, Components Are Extra):
Standard Grade Mechanical Watch Overhaul Includes: Dis-assemble, Clean Movement, Inspect, Replace mainspring and bad/worn components, Clean Case and Band, New case back gaskets, New Spring Bars (if applicable), Re-assemble, Lubricate to manufacturer specs., Timing Adjustment and Water Resistance Testing (if applicable).
Pricing starts at $465. Components are extra.
This is only a starting price to give you an idea of the cost. An Estimate will be provided once the watch is inspected.
Your mechanical watch will be cleaned in a specially made watch ultrasonic cleaner except for the balance wheel, hairspring and pallet fork which need special care and cleaning. Hairsprings are cleaned using a special hairspring cleaner. Any oily residue left on a hairspring if cleaned in the ultrasonic will make the watch impossible to time. If the balance wheel is run through an ultrasonic cleaner too many times or for too long it will become lighter and that will make it impossible to time the watch. If material is removed from the balance wheel by an ultrasonic cleaner the only correct cure is to replace the wheel.
This happens at 'watch breaker' shops where they do swish and lube cleanings because they do not disassemble the movement.
Timing of your watch is done with a digital timing machine made by Witschi. Automatic watches are then placed on watch winders and kept running for 2-3 days and timing is checked to make sure the watch continues to perform as required.
NO corners will be cut. I will do NO rush jobs. Quality Canonot be Rushed.
My reputation is on the work I do. I will do the job right or I won't do it at all.
NO estimates of any kind will be given unless I have the oportunity to examine the watch.
NO exceptions.

Other services available for your Seiko Watch:

Crystal Replacement
Including genuine Seiko crystals and after market plastic, rock glass, mineral glass and sapphire, custom cut crystals, anti-reflective coated watch crystals.
If your wrist watch has a flat or domed round "mineral glass" crystal currently, a sapphire crystal may be available that will fit your watch and a sapphire crystal will give you a virtually scratch resistant crystal. If your Seiko watch has a plastic crystal in it now it cannot be replaced with a sapphire crystal.

Crown, Stem, Pushers and Case Tube Replacement
Genuine Waterproof, Screwdown, Divers and Colored Stone Crowns. When these components are worn, stop sealing or if you want a different style, we can replace them for you. Genuine stems and case tubes replaced. Pushers rebuilt or replaced.

Dial Refinishing
If the paint is coming off your dial or the luminosity is no longer working or if you just want a different color(s) on the dial then refinishing the dial will make it look just like new and give your watch that look you desire. Repainting the luminous will make it easy to read the time at night or in dark places. I offer many different colors of luminous and can mix different shades to suit your desire.

Hand Replacement
Maybe the hands on your watch are bent, maybe the luminosity is no longer working on your watch hands, maybe the hands are damaged by moisture or maybe you just want a different style or color so you can see them better. We can replace the hands or repaint the hands and repaint the luminous so they glow again.

Retrofitting is when a quartz movement is used to replace a mechanical movement in the watch. This requires a good deal of research to find a quartz movement that will work correctly in the case and with the dial and hands. Due to the wide range of costs for movements pricing is only quoted after we determine which movement will work best in your watch case.

Yellowstone Watch Repair BBB Business Review

Our Customers are saying:
I am a repeat customer of Yellowstone Watch Repair and can say without hesitation that Ken and Kristi have been wonderful to work with. They have responded quickly to my queries and performed their work exactly as promised. Ken took the time to provide professional insight and advice when I had a question regarding the feasibility of installing a domed sapphire crystal on my Seiko Arnie. His reluming work on the Arnie was flawless. Ken's website and blog are a wealth of information and a must-read for anyone who does not fully understand the concept of water resistance in the watch industry. Yes, I highly recommend Yellowstone Watch Repair.

Hey, how you doing? Hey? This is Jim Mahoney. I had just received my watch today, a Seiko. And I want to say thanks it's a pleasure to deal with a company that does what they say they're going to do because so many places say one thing, but you don't really get what they say. And I just want to thank you for that. You're just somebody pulled out of the internet you know and and you did everything you said. You did a wonderful job on that watch. It's running like a clock is supposed to run. Thank you very much. It's nice to deal with a reputable business. Thank you very much Jim Mahoney again. Thank you.
Thank you very much! I received my watch on Monday. Working well and looks like new!!! Thank you!
The Postman dropped off my Seiko Quartz today. It is working fine and looks great. Thank you. Robert J. Buhl
been meaning to write, the watch is great! We are happy it was saved....My wife is tickled to death Thanks , Barry
I just received my Seiko watch in the mail. WOW!!! I am IMPRESSED! It looks as good as ever ... shiny and "new", and very smooth operation of all the controls. It was well worth the wait! I'm sure the watch will provide another 10 or 20 years of service, baring any catastrophe. Extend my many thanks to the watch maker(s) for the excellent work. Have a great day.
Mark Smith
"Thnx" so much for the beautiful new crystal, as well as repairing the hour markers on my Seiko. Received it back about 4-5 weeks ago. Regards,
Dennis S. Morgan
I wanted to let you know that my Seiko chronometer has been working perfectly since itís last trip to your shop. The stopwatch function no longer interacts with the main time and all other functions work just fine. Thanks for a job well done. Happy Thanksgiving,
Wanted to let you know I received my watch yesterday in the mail and thank you so much. It looks like the first day I got it. Thanks for the excellent service.

Just a note to say I received my Seiko Sports 100 back, and am very pleased at your service. Everything got done that I wanted. It looks refreshed and ready to go for a goodly time to come. I bought it in 1979.
Thanks! Art H.
Just a note to say thanks. Timepiece arrived today (as promised). Looks great, adjusts smooth, on my wrist as I am sending this. Appreciate your craftsmanship, not to many people like you around. I will sure pass your name on to anyone who is looking for quality, professional work.

I received my repaired Seiko from you and it looks, and runs, great. Thank you for the quality work you performed - I truly appreciate it.

I would just like to tell you that my watch has been back here for a couple of weeks now and it works great. I don't think it worked this well even when I first bought it..
I have a very old Seiko that I received 35 years ago that still works and when it comes time I'll be sure to look you up again to request that you service it also.
Until then thank you very very much for an outstanding job !!
Sincerely, Bob M.
