Rolex 1520 Hack Feature not working


Recommended Posts

We would need to know the movement number of your watch the 5513 is a reference number not the movement number. Then we can't really determined the parts until you take the back off and do a partial disassemble of the movement.  Then usually on the watch like this if it hasn't been serviced in a while a full complete overhaul would be recommended.

From my point of view there are many reasons possible. Here a picture of that spring, which is driven by the setting lever and slightly touching the balance. Engagement to lever could have slipped out, spring broken, spring bent, screw loosened ...

I think you have to strip down the movement at least half the way to find out whats going on. So a complete service would make sense.

I'm in agreement with Delgetti. A strip down is necessary to find the cause of the spring malfunction, so a service makes sense whilst doing that

I have a link to someone supposedly servicing a 1520 but it's missing the hack?

Then I'm attaching PDFs for the 1520 and the base caliber 1530. Also attached is a service manual ancients one which on  PDF page 7 shows the hack mechanism and how it's supposed operate.

    • Try putting everything back together and closing the back cover. I think one of the two springs has to contact the metal casing to ground the casing. So when you press the button, it will touch the contact on circuit board and close the circuit.
    • Yes, the seconds hand is the longest and goes almost to the edge of the dial. I can’t quite picture it how you do it on the rubber pad
    • A don't think so it leaked or damaged it because the watch itself works it just the buttons ain't working not connecting with the circuit board have taken more pictures of where the buttons makes contact with the circuit board.
    • I think what peter means oh is once he has fitted the hands and  checked for  alignment if them and that they dont foul, how does he then hold the movement to remove the stem in order to case up. The dial cannot be laid on a cushion or in a movement holder as the hands will get damaged. This can be quite tricky for a beginner, what i do is  to stand the movement on edge on a rubber pad so it doesn't slip. Hold the top edge with one finger then my dominant hand uses 3 fingers to press the stem release and flick out the stem. See below peter, leave off the second hand as this is the longest and gets caught the most, then fit it once the stem is out. Alternatively place the movement in one of the cup style holders, i imagine this is what they are designed for. They only touch the very edge of the dial.  
    • Yes I understand that. What I’m asking is, after the hands have been fitted, it’s been checked that the hands do not touch etc. then I need to remove the stem to fit the movement in the case. I have the push type, I need to turn it upside down and push the setting lever post and pull the stem out. But of course the dial and hands are in place and I have a glossy dial with lume dots and I do not want to cause any damage while it’s upside down pushing on the post of the setting lever.
