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?
That lever is for silent or strike. You have to make sure you have the wheels in the correct position both chime and strike in order for the chimes and strike to work. Also the cam wheel on the chime the gathering pallet on the strike. If you need help with this movement I can help you through it, just ask.
@HSL demonstrated how he disassemble, clean and lubes reversers. I am looking for his post, hopeful to find it and will inform you.
Considering your watch is a Tudor, I personally prefer and recommend new replacement.
If your mobile phone is in a flip case with a magnetic catch then all you have to do is leave your watch sitting on top of you phone for 5 minutes and bingo.... it can be as simple as that unless the watch has magnetic shielding.
Either way magnetism or sticky residue on the H/S are you most likely causes.
