My dad's Sub died

This is a watch that my grandpa has passed on to my dad before he died. It has a great history as it was originally purchased by my step uncle in 1981 and due to some financial difficulties in the 80s, he sold it to my grandpa and it has been a daily wearer.

I'm early 2010s, my grandpa passed on and the watch now belongs to my dad. He has also been wearing it daily and few days back he told me his sub stopped working.

Anyone knows what could be the common problems?

Could be a number of reasons. It probably just needs a regular full service. Should run like new after.

If you get it serviced make sure they don’t touch that case, edges look great

What's the difference between a regular service and an overhaul?

Some people use the terms interchangeably but for me, a simple service might involve minor work and lubrication that wouldn’t replace items inside.

An overhaul includes the complete disassembly of the movement. The case and bracelet are ultrasonically cleaned, polished and refinished to remove marks and scratches. The movement components are inspected for wear and worn out ones replaced. The mainspring and barrel are replaced. The movement is ultrasonically cleaned, and then reassembled using specific lubricants. The movement is electronically calibrated and placed into the case with all new gaskets and o-rings. The completed watch is pressure tested to check water resistance.

Good explanation. The movement is a 1575. Was wondering if any of the parts need to be replaced, how will an independent watch maker source for it?

For most people "full service" and "overhaul" basically mean the same thing, but there are subtleties at the margins, so it's best to be totally clear about exactly what work will be done. Don't use jargon and code words with your watchmaker unless you have been working together for years and he has serviced many watches for you. Have him talk you through the whole process and make absolutely sure you're both on the same page.

A small number of independent watchmakers still have Rolex parts accounts. Ideally you would use one of them.

Well since it “died” then you can expect some parts must be replaced. I would be prepared to pay for some escapement parts as that is often the source of stopped movements. Certainly replace mainspring and barrel as a routine maintenance item. The crown and stem may need to be replaced too but sometimes that can wait. The crystal too, if it’s cracked or no longer able to be buffed.

In Singapore you have many watchmaking resources but only a few may have an authorized Rolex parts account. I’d insist on genuine parts.

So it would be inevitable to replace some parts then? Am hoping will be able to salvage and retain all original parts..

I think we are mainly talking about the mechanical parts of the movement, and you won't know if parts need to be replaced until the problem is diagnosed. There are dozens of parts in the movement ... wheels, pivots, jumpers, screws, springs, balance, auto-winding mechanism parts, etc., etc. Maybe nothing is broken, and just completely gummed up (although that seems unlikely), in which case a full service will take care of it. Or maybe it's something really simple, like a screw has come loose and is jamming the mechanism. But if a mechanical part is broken it usually must be replaced, preferably with an authentic replacement part. This is standard and necessary if you want the watch to function properly. You can keep any broken parts that are replaced if you want. We are not talking about external parts like bezel, crystal, or hands which are mainly cosmetic and replacement is optional.

It simply needs a service.

I would not bring it to Rolex, have it serviced by a good independent watchmaker that realises that the watch worth is in its originality.

Don't polish it and don't have any parts of it exchanged. I'm not talking about the exterior of the watch. Since it stopped parts of the movement will probably need to be replaced with new parts which is ok.

Yes some parts must be replaced over time. At the very least, the ine(s) whose failure led to the movement stopping.

I respect your thoughts about keeping it all original but in truth some parts wear out and must be replaced. For example a broken mainspring or perished gaskets.

If this is a feeling you have about the spirit within the parts, then ask the watchmaker to returned them.

Or keep the watch just as it is, save the S$1000-1400 and some future heir can tackle the resurrection.

You seem familiar with the Singapore Market. Any good independent watch makers to recommend?

Good looking watch. Try to keep it that way. Just get it running properly, of course.

For info, the dial is already a service dial.
Do you have any service receipt with the watch ? (it seems that most documents were nicely kept)

I do not have any other service receipt. How can you tell it is a service dial?

Cutting to the chase for the OP...

The top image is an original dial
The one beneath, a service dial

Note the open 6’s in 660ft, kerned text, plus the spacing in the 3 horizontal lines making up each “E” in SUPERLATIVE CHRONOMETER in the service dial.

Best way to find out what is the problem with the watch is to bring it to a competent watchmaker. It has probably not seen one for quite a long time.
I would not polish the case as it looks still very nice.

Are you able to check if the lume is tritium or Luminova ? (Reaction of dial, hands and pearl to UV light)
