I need to source a "Date Indicator Maintaining Plate" #0808-300 for a 7S26 "C" movement. I'm building a franken movement out of an "A" and "C" model and Seiko changed this plate. Any ideas as to sources?
Hello dear watchmakers.
Last week, I was lucky enough to get my self a beautiful vintage Seiko chronograph watch with 7015 movement.
The overall condition looked great so I did not expect any problem with the watch.
However, over the last few days, I noticed that this watch stops around 1~2am when the day disk moves to the next day.
At first, I thought there was no residual power in the mainspring but the watch won't start after being shaken for some time.
It runs well and keeps good timing after I move the day disk manually by adjusting hands by crown till the next night around 1 am.
Could you please give me any ideas on this issue?? I really love this watch and want to make this watch perfectly functional. Thank you.
I put some photo of the watch and what timegrapher tells
I'm new to the forum and watch repair. It's great to have a resource like this when things aren't working as they should!
I recently bought a 6119-6400 with a couple of known issues that I'd appreciate some assistance with.
Firstly, the internal bezel is very stiff, it turns but with quite a bit of effort. Secondly, the quickset date works, but the crown sticks once pushed in and the day won't change when the crown is pushed. It does advance when changing the time between 9pm and 1am though.
Lastly, I confess I'm not much of a fan of the hardlex crystal and would love to try a slightly domed sapphire (it's a UFO, right?). How do I find something to fit, any suggestions? I have the sense that trying any old 33mm crystal is unlikely to work.
Thanks in advance for any help you can offer!
I have a seiko 6139-7100 chrono, the watch was serviced twice in the past three months by two different watchmakers and both can't seem to figure out the problem, the watch itself keeps excellent time, but the chronograph is 2-3 seconds fast a MINUTE, which is crazy, any ideas on what is the cause? how can the time telling function of the watch be keeping accurate time while the chrono is not?aren't they both supposed to be depending on the same 4th wheel?
I had one of my watches (Longines Hydro C.) on the timegrapher, and in dial up position it made a rather weird fluxation.
Stabilizing at around +003 and holding this rate for 20 seconds or so, suddenly and only for a fraction of time, it jumps down to -13, for then fluxating - just like that - up to +003 again. Then it stays like that for about 20 seconds, for again jumping to -13 and back to +003. And so on and so forth.
Why is this? Is this normal?
It could be mentioned that this watch has held an accuracy while worn about 1.2 s/d, but after using the snowblower (and sadly forgetting to take off my watch) which shakes and rattles like crazy, the watch has lost one second. I am thus worried that this might have impacted the performance of the watch.
Is my fears justified, or is such influxtions rather usual? I have no pictures for the moment of this weird reading. I used a witschi watch expert timegrapher.
Thanks in advance for your thoughts!
Really? 0.01mm? Maybe inches??
I just grabbed a largish looking one out of the packet. The head diameter was 0.6mm and the pin length (minus the head) was 2.3mm.
The packet really does have quite an assortment with different head and pin lengths and diameters.
I would send you one if you knew exactly what you needed, but some of the heads are tapered and some straight, so if this sounds about right then you might find it best to get the assortment to choose the best fit
