Hi everyone. Some vintage oris stop running not long after cleaned, I am sure the problem is common with vintage oris 677 kif and 704 kif.since I got many of them. I think of worn down staffs or weak main spring as the cause.
Interestingly dropping one drop of aircraft fuel on top of the upper and lower jewels of balance wheel only and it fly like combat jet.
Lots of hope to recieve your opinion.
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?
I've only made 1 balance staff so far.
I've got a German aircraft clock that has a broken endcap jewel that also had both ends of the pivots worn flat. I've rounded them again and once I've received the new reamers for my jeweling tool and fitted the new endstone I will find out if I will be making my second balance staff as it may now have too much endshake.
Thanks. Not sure how I would advertise? I actually love making balance staffs. The new DSZ-70 stereo microscope is great for examining my work and seeing any defects in the parts. Still cutting the part with x20 loupe however. Here is my messy desk Sent from my iPhone using Tapatalk Pro
