      Hi guys,
      Thought I'd share some pics of my Oris Big crown with pointer-date (circa 2009?).
      Simple classic design and quite in the spirit of the older Oris watches.

      The case back gives a good view of the ETA2836 inside. The red rotor was a Oris touch. The edge of the caseback has a coin-edged design, similar to the front of the watch. This improves the look of the caseback as the metal edge would look too big otherwise. Increasing the display window wouldn't work I think as that would only show the movement holding ring.

      The line is still pretty decent..

      And the bracelet is nice and supple.

      But the design of the clasp is a bit plain.

      Oris deserves credit as it was one of the brands which was instrumental in bringing back the Swiss watch industry back from brink of the abyss. In the late. 80s and early nineties, their classically designed watches using ETA movements sold well by focussing on the mechanical movements and using it as their USP. Their tag-line at the time was 'high-much', as seen on the rotor in the movement pic above.
      This watch came my way as a part exchange for an Omega Constellation. The previous owner had gotten the Swiss watch bug but as he got deeper into the hobby he started to appreciate other brands. To be specific, he was  getting into the 'manufacturer' brands as opposed to 'ebauche' brands. It's a shame as this watch is quite good as it is. Ah well, the previous owner should be into Pateks by now!.

      Can't stop wearing it !

      Yesterday my Oris watch hit a tiled floor when the strap pin broke and the back crystal popped off. Being in a rush , I quickly pressed it back into position and left it for later investigation.

      Today the crystal seems to be fixed in position, but I have no experience of removing or replacing these. Was a simple press of the thumb strong enough to do the job? How can I check, other then testing with my thumb nail. Are these a simple pop on fixing?
       
      Many thanks.

    • Hi Luiz     I have attached tech sheet for the 560  Not your caliber but it  shows the part. 3422_PUW 560.pdf
    • Hi Luiz  HSL is correct the inner ring  is missing and the screw locks down on to the crown wheel not the ring. The part is numbered 422  and known as the crown wheel ring. 
    • Just took a look and PUW movements in general has a crown wheel with a small bearing. And by the looks of your ratchet screw I would say it is missing the small bearing and is upside down. I just pop a picture on a common PUW ratchet wheel here so you can see what it might look like.   
    • Crown wheel of course.... screw has no shoulder probably the washer was then lost.  I am learning... very slowly... went to bed 4:15 this morning. I was shocked by the result after the cleaning i guess i must pay the price of the knowledge. Very painful so far and not much knowledge gained, well to my former myself i go with lightspeed but it is just not enough and they say there is no 2 x lightspeed. 
    • 1-Imperfect hairspring coil can foul itself when amplitude gets too high so the rate goes fast , until such time that  HS coil jumps back to normal.  2- Loose and pushed back guard pin, fails to guard the roller table- impulse jewel properly, in which case if the balance wheel gets in a hurry on wrist it is susceptible to the condition in section 1.  Faulty guarding by the pin, can let the condition for sticking to come about.
