A .99 cent purchase . Guy said it needed a battery. Hmmm. Just a wind.

Don't think my photo is showing up? Will investigate further. Photo size may exceed limits. Anyway...99 cent Marvin from late 40's. Great piece. This is my first post and I'm looking forward to being here. I really want to be able to clean and work on my watches.

Photos to come !

Thank you for the kind welcome. Actually I have another Marvin from that vendor and as they both work they are losing 3-5 minutes a day. I will be glad when I can disassemble and reassemble with nice cleaning and lubrication.  I am reading as much as possible and look forward to the next post!

Today! Gains about 30 seconds a day. In need of a cleaning.

30 seconds is not too bad at all. The cleaning may remedy that. I've got two of my repairs under observation to try to get them regulated for optimal performance. Right now one is within 1 minute from quartz timie, and the other goes from 3 to 5 minutes off AFTER cleaning and oiling. I guess I would be OK with 30 seconds to 1 minute deviations per 24 hrs--yup.

One of the Stargate Seikos I restored starter gaining about 10 min a day after cleaning and all. I thought being a Stargate it was giving me the time in another planet! :) When I looked closely there was a drop of oil shorting the hairspring. Once I cleaned the whole balance and re lubed, it started working fine....

 

So maybe on both cases, it is just the hairspring coils touching!

  • 4 weeks later...

marvin's are great value...you will usually find the movements marked 3 adj or 5 adj. This means that they left the factory with additional work done to ensure that the run accurately!. Practically chronograph grade.

 

Also they are a true manufacturer and I have not come across any ebauches..(mechanism made by other companies like ETA, AS, FEF, FHF, ST) so they are quite high quality.

 

Be careful not to drop it as most of them date from the fifties and do not have any shock-protection at all.

    • Sorry I'm back again the reason why had   push the jewel out was someone had fitted a wrong one a couldnt get any end  and side shake with the old one ...I'm replacing it.
    • Tah-dah. A mini blow torch to harden it, then quench it and just a lighter held under a brass mainspring barrel that the part sits in to temper, Its important to wipe off any grease from fingerprints with ipa, you might be able to see i missed a bit at the top of the arm. Its a very satisfying process. I now just need to deal with the more difficult repairs, anybody any good at replacing rubbed in jewels ? 🙂
    • No I haven't tried that, I'm just thinking of the most complicated solutions 🤣   Another great idea 👍 All I need to do is hold that little bugger steady while I try and screw it in, without starting to shake, it gets the better of me sometimes but is getting less the more I do 😀  I need to order some bits from Cousins so I decoded to put this to one side until I get a balance screw holder, it may come in useful later on as well. I'm assuming it closes down enough as I don't know the diameter of a balance screw compared to the stud screw, I haven't worked on a movement with balance screws! I'll be getting the cheap one 😆
    • Finally figured out why my hands are so god damn steady. My mum 87 years old , 4 weeks after her stroke and has a macular hole in both eyes, she wiped the floor with me and my lad at a kids stacking chairs toy game. Here she in rehab placing the last chair into position, bloody ' Supergreatgreatgran'  i hope I'm half as fit at her age 🙂
    • Punch a hole in some thin card, push the screw through.  Start the screw and rip the card off
