Service: Rolex Submariner calibre 1570


I’m starting to blog about some of my jobs for customers as I can’t be working on my own watches all the time;) Andrew sent in this vintage Rolex, it stops intermittently and someone had a go at changing the bezel ring insert. 


Someone tried to punch the replacement bezel ring insert in place:S


I remove the bezel ring.


Amplitude is good, but there are fibres in the movement.


Movement is not too dirty but full of fibres.


I start by removing the autowinder mechanism while the movement is still in the case.


I then take the autowinder mechanism apart.


Setting/winding mechanism being taken apart.


Movement coming apart.


Gear train visible after removing the train bridge.


Old mainspring.


Parts have been cleaned. Here I have fitted the balance jewels back in place and see that the balance swings freely.


Here the movement is already back together ready for dial and hands.


I like the design of the Submariner dial.


Base movement back in the case ticking like it should.


I’m happy with the performance (I’m embarrassed I had not cleaned away the dust from the screen)


Autowinder mechanism is put back together.


Complete movement back in the case.


I have replaced the bezel ring insert and it just looks much nicer!


I would not mind owning one of these myself!;)

    Another lovely repair Mitka. A silly question, if I may. Looking at this Rolex, most of the internal parts seem to be made from steel? Looking at some of the other repairs on the blog, some watch parts seem to be made from brass i would think ( Lemania) – the older Longines 12.68 seems to be a different colour and perhaps metal. Are they made from predominantly different metals and does this make a difference to longevity, accuracy etc., or does it make no difference at all.

      Not a silly question, almost all the movements are made out of brass, but are plated in different ways for decoration and to protect the brass from corrosion. This Rolex movement I believe is Rhodium plated. Wheels are usually brass and the staffs and pinions are made out of hardened steel.

    Thank you – that is most helpful.

    Hello Mitka,

    I would not expect fibres to end up in a watertight watch with a screw down crown. Any idea hoe they got there?

      Option no 1 owners get curious on how there movement looks like. Option no 2 watchmakers are sloppy. Looking at how the bezel ring insert was fitted I would suspect option no 2!;)
