      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!.

      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.

    • This should do the trick, spare pins available. https://www.cousinsuk.com/product/oilers-3-in-1-incabloc-specialist?code=O49486
    • Are you going to route a little 'trench' across the front edge of the top to catch anything that trys to roll off the front?   Coming along nicely.
    • Found a watch part, i wonder if it is good for the PUW 60.
    • Morning all. Thanks for the kind advice and warm welcome. @Nucejoe I've tried to give the watch a shake and the second hand remains in the same place (just before the 45 second mark). It's had a full wind and it certainly feels like it's not holding any power. We'll have to see what it looks like when I can get the back off it. I'll let you know what movement is inside so I can take a look at the datasheet and get cracking! Bring on the postman!
    • The measurements of the original Orient/Seiko mainspring are as follows: 0.95 x .115 x 370 x 10.55 Automatic (Height x Thickness x Length x Barrel Diameter) The closest replacement I've been able to find and the one I've been using is a Generale Ressorts spring: 0.95 x .12 x 400 x 10.5 Automatic The only lubrication I've done is the Kluber P125 around the barrel wall, and I do not lubricate the spring as it comes pre-lubricated. As far as I can remember the bridle of the GR spring and the original spring look the same or very similar. Unfortunately, I cannot verify this as I no longer have the original spring (per usual I mangled it in my K&D winder). And yes, just to make sure, I have no reason to believe the arbor hook slips out of the eye of the inner coil. If it did, the spring would unwind in an instant and it doesn't. When I wind the ratchet wheel screw using a screw driver (this watch isn’t hand wind able) it feels very smooth and the only plausible explanation, as I see it, is that the spring is constantly sliding as I wind. No mater how many revolutions I make on the ratchet wheel, unwinding always results in 4 revolutions of the ratchet wheel before the power reserve is depleted.
