Mineral oil should be ok for 5yrs and synthetic for 10 years providing:-

Keep in sealed container, preferably glass.  Metal containers may deplete any anti-corrosion, passivating additives in the oil. Plastic maybe ok but some oils will react with plastic so best avoided.

Keep stored in cool, dark place which stays fairly constant  (heat will oxidise the oil  quicker and very cold may cause water crystals as most oils have some very low levels of water in them).

Try and keep the container as full as possible to reduce the amount of air (the air will enable oxidation).  I always store mine upside down to avoid ingress of air through the cap, (the air could be moist), believe it or not air will get in as the temps change and the air 'pumps' in and out but the oil will not leak out !!  As long as the cap is covered internally with oil then this is ok.

Pour or drip the oil out when required and avoid putting anything in the oil as this will likely introduce dirt.

High quality oils should last longest.

      Setting lever spring

      By mikepilk · Posted

      I would harden and temper (to a light blue). It's so easy to do and only takes a couple of minutes. A search on ebay UK for "spring steel strip cs" finds plenty available in small quantites and thicknesses from 0.1mm up.  But the question is ( @nickelsilver) which "CS" number is best for watch parts ?  Also, from one of the ads : "CARBON SPRING STEEL. SIZE IS METRIC 15.00mm X 0.10mm X 304 MM  CS100 FINISH BRIGHT . HARDENED AND TEMPERD TO 480-530VPN" I've no idea about 480-530VPN. Does that mean it needs annealing before working?       Have you seen this video, he shows how to determine where the indents go ?

      Here is the insert ring for rectangular or elliptical movements: Note that the length is the side with the stem cut out on the spreadsheet (in the picture below this is 15.15: Here is the fake pdf file, again you need to convert to .zip after download to access the FreeCAD and 3mf files.

      Omega cal. 565 - low amplitude

      By JohnR725 · Posted

      as you took the mainspring out what did it look like? It's amazing how much amplitude you can get if the mainspring actually has the proper shape. last week I was doing a 12 size Hamilton and was very much surprised with the beautiful back curvature the mainspring had. Then the watch had a really nice amplitude the group would be so proud it was 350 until I dropped the lift angle down to 38 that drop the amplitude quite a bit below 300. then with the beautiful back curve it still had really nice amplitude the next day. I really wish all my mainspring's look like this as the watch had beautiful amplitude the next day. So many of the aftermarket pocketwatch Springs I see now do not have anything resembling a back curve may be a slight curve and that's about all. They still work but they just don't work as nice as a properly made spring. then Omega as all sorts of nifty technical documentation unfortunately every single corner is watermarked with where it came from who downloaded it etc. very paranoid company. On the other hand I will snip out images like from the document on recycling a mainspring barrel. for instance here's the section on what your mainspring should look like. water damaged a lot of times means rust was there rust on this watch?
