strap pin repair/replacement

Hi Everyone,

I have a nice little Uno vintage watch that has a broken strap pin.  The case is only base metal and the pins appear to be cast into the lugs.  What would be your advice for repair or repair?  Many thanks for your help.

An easy repair, so to speak. You just solder/weld a new lug pin. I guess you have to remove the remaining bit and then polish or file the area to flatten it and then you just solder a new one.

Hi Chopin,

thanks for the speedy reply!  I'm assuming I could just use a little piece of bar stock of the correct diameter from my materials supply company?  Thanks again for your help,

Peter

As Ishima points out you'll have to do a bit of research to see what type of metal to use and what type of technique to use as there are a few out there. Maybe laser welding might be a good and clean job with no excess metal gather around...

Yes, absolutely.  I have no jewelery soldering experience - only electrical.  It would be a skill worth developing.  Youtube is a great resource!

If the base metal is brass then it’s pretty easy. I use soldering paste and stainless rod. Use calipers to measure original rod thickness. 

Hard soldering is a skill, and you should definitely practice soldering a spare piece of your rod to another similar scrap base metal like your case. 

As it looks like a cheap watch though, you may be best going with JDM’s suggestion and just pierce the lugs to allow spring bars to seat. The holes will deteriorate if they are unplated brass though. Seen it happen enough times.

Yes - drilling the lugs is looking more attractive.  It also plays more to my skill set.  It is a cheap watch and the case feels like a die-cast metal so it shouldn't be too difficult to drill.  Famous last words....  I'll post pictures either way!

Thanks to all respondents for your advice.

    • Learned a new thing today! 🤓 Looked this up and found this informative document: Watkins-MainspringGauges.pdf
    • Correct one dip is expensive when the chemical is purchased as " one dip " which is why it is mostly reserved for these two small parts as far as information tells us it is mostly tetrachloroethylene. I use it bought as perchloroethyl used in dry cleaning processes, i cant say I'm overimpressed with it though it appears to me to be shellac safe. What may be a better solution for hairsprings is a high lab grade of pure benzine.  IPA is mostly used as a rinse and water displacer and yes it does have the potential to dissolve shellac, personally i would not buy anything that has significant water dilution so 99.9% IPA is the way to go. And lastly the part you are cleaning dictates your choice of cleaning brush, delicate parts like a hairspring requires the finest artist's brush you can find. Plates and bridges can take a little more scrubbing, but always check to make sure the surface is being unharmed. And dont forget a stick of tip benzine soaked correctly shaped pegwood is your mate set up for cleaning dirty jewels and removing stubborn dried up lubrication. 
    • Hello and welcome from Leeds, England. 
    • Den / Dennison is a unit measurement of size this is actually a mainspring gauge . I haven't heard of a pivot been measured in Dennison before.  Though the small thickness gauge is  usually supplied with a Jacot tool and is more accurately known as a pivot destroyer.
    • Could it be an abbreviation for Denier? "Denier (/ˈdɛniər/) or den (abbreviated D), a unit of measure for the linear mass density of fibers, is the mass in grams per 9,000 metres of the fiber. The denier is based on a natural reference: a single strand of silk is approximately one denier; a 9,000-metre strand of silk weighs about one gram." The pivot gauge looks interesting, however I wouldn't trust myself to drive a pivot into a wedge incase it jams and gets damaged/snaps trying to get it free. More a comment on my ability and incompetence than the quality or design of the tool 🤣
