Just Completed Second 7548 Diver


Recommended Posts

Just completed a complete refurb of a Seiko 7548 Diver 1981, and for a friend. Here are some pics.

So I completely pulled this apart, cleaned it with lighter fluid by hand the slow way and rebuilt and oiled it. Lots of fun with the mix of electronics and mechanical parts. The stepper motor is so small. Hardest part was putting the new hands on. I also had to spot glue the new bezel insert as it was a bit loose. Buffed the case from all dents and scratches with a variable speed drumel tool using #2 grinding polish. Replaced the crystal.

Was it difficult getting the crystal back? I usually don't look forward to this on Seikos...but still better than those crystals held on with the small plastic rings.

I did all the right moves by buying the right crystal for a 7548 and a new L shaped gasket and then using a crystal press to press it back into place. I was very careful not to press the crystal but the outer ring.

jdrichard what make of screwdrivers are you using looking at one of your pictures they look a fine set.

These are really good really cheap from Esslinger. Deluxe Fixed Blade Miniature Watchmakers Screwdrivers Individual Sizes

Starting At: $2.59.

I hate the screwdrivers that have a side screw to tighten the blade.

you done a great job. could you post any detail of the process? I am interested in

Yes I will. I have the full process documented on my facebook site as well as many videos on YouTube on what I did. Look up jdrichard01 and ignore the music and magic and look for my watch repair videos. I am new at this but have done a ton or reading and practice. Currently I am working on a 6139 Seiko Chrono fully automatic. Big job but almost there.

    • Thank you for your introduction and welcome to this friendly forum. We all look forward to your contributions and continued involvement. 
    • Have you now repaired it? If so how is the time keeping.
    • Yes: that's it exactly, right down to the break in the spring!!
    • I've bought brands like Citizen, Seiko, Titoni, Tissot, Roamer. Strange thing is many of them were using ST96 movements. I'm not sure if the ST96 is original to that model or whether it was a replacement movement.  All the watches with nice looking dials were obviously refurbished, after-market dials. And all of them had over-polished watchcases. Some of them had non-original hairsprings, rejewelled pallet forks, watch crystals that don't fit and glued in with a generous amount of glue. One of them was totally not working because the pallet jewel was loose to the point that it almost fell off. But the sellers were very nice. The seller of the non-working watch gave me a complete refund. Some of them gave partial refunds. I would say don't by luxury watches on the internet, regardless of the country the seller is from. Don't believe the "serviced by master watchmaker" statement. Have realistic expectations. ( Do expect the occasional complete junk.) Do expect to do a complete overhaul and major repairs. Otherwise, watches from Mumbai are great. For clocks.... I'm not so sure.
    • In 2020,I picked up an Orient Mako II online. It ran at +15 seconds per day and after 3 years of resets more than weekly, it was time to crack the seal and take a shot at regulating it. Not having a timegrapher, I used a spreadsheet to track the time, referenced the Canadian NRC website, wore the watch between adjustments, and used the back end of some tweezers to lightly tap the regulator daily until it ran to within one second per day.   Two months later, it’s still running to within 1 second per day when measured over a week or longer, while daily variations are up to 9 seconds per day. For my purposes, its overall stability is surprisingly good. Is this method of adjustment “better” than adjusting to 5 positions using a timegrapher, since during the adjustment period the watch is already in the environment in which it’ll be used?
