Seiko 6138 - Quick set date doesnt work


Khan

Recommended Posts

Hi 

As per video, the quick set doesn't shift the date wheel but turns the wheel for day wheel. Feels like there is not enough force in the wheel at 3 o clock that turns the date wheel. The two top plates levelling the date disc are not overtightened. The date changes when turning hands 24 hrs or by moving the disc manually by finger without resistance. Any ideas? 

Thanks

Hi Melt

Thanks for the tip. I have actually seen those two plan designs of the upper wheel on the so called "wheel lever complete" (the one I have and the one you referred to on image). From a side view, that date changer wheel system consists of two almost identical wheels and the wear is in between these wheels in a way that the date disc is slipping through and doesn't shift. So I have to order a new. These are not easy to find.

I guess you could fill the gap with a chemical metal......worth a try if you can't find a replacement.

    • If frank says these bombè jewels are for balances and similar pivots then they are used cupped side facing the pivot and then capped i assume. In Nicklesilver's reply i guess that cup can also be reversed and used as an oil reservoir leaving the shoulder riding on a less frictioned domed surface. 🤷‍♂️ Hence the use of them on wheels closer to the escapement that have less torque requiring efforts to reduce friction and are also uncapped.
    • Looks that way, if it had any amount of significant jewel count it would say so on the dial.    Looks that way, if it had any amount of significant jewel count it would say so on the dial.  Same answer as Mike regarding the dial, its often just a slapped on name of a retailer but i thought you were way above this understanding Pete ?
    • Light naptha is what you need to be looking for. The carbon to hydrogen ratio is high with heavy naptha, it doesn't evaporate as well as light naptha and is prone to leaving more residue. Try tom's suggestion of the mirror test.
    • Its a big item Michael and a lot that could go wrong with the process of getting it to its new location. I once helped install one of these units into a conservatory that i had built. It was big and bloody heavy and took six of us to get it in safely. If you have sliding doors and you need to remove the whole frame then that may or may not go well. But i would advise getting a professional in if you have little knowledge on the installation of them. The glazing of the doors could well be 6mm laminated glass which again will be heavy very heavy if the glazing units are big. The glass would also need to be set up and packed correctly to open the doors properly more so if they are unframed and the sliders are upvc. Seems a shame but if no one is biting and that may be due to having no warranty i guess the only takers might be someone that installs them for a living and knows how to repair. If its fibreglass just be careful, i sometimes have to cut fibreglass baths out and they are nasty to work with . Thick gloves are definitely recommended,  not fun picking out fibreglass spells two days later that have started to go septic. Good luck with it all matey.
    • I don’t know anything about this product, however assuming you have it if you put a drop on a mirror or piece of glass lying flat on a table and leave it to evaporate if it leaves any sort of residue it is not really suitable for watch part cleaning.   Tom
