Kluber Chronogrease P125 - Expiration date

[VWatchie]

Despite the staggering cost of £15.600/€17,380/$19,472 incl. tax per kilogram for this wondrous grease I'm considering getting myself 5 grams of it, which is £78/€87/$97 only!  (CousinsUK.com).

However, if it expires within a couple of years I'm out. So, my question is; does Kluber Chronogrease P125 have an expiration date? If it has a durability of at least 5 years I guess I might be able to swallow this bitter, bitter pill

one of the complaints used to be when purchasing moebius lubricants other than the price of course was how old is it? Look at the old bottles none of them have dates. You spend a lot of money on something that you have zero idea how old it is. Then a lot of their lubricants like I think all of the 8000 series is mineral oils with natural substances and there is the possibility that that will disintegrate or do something bad with time.

then what exactly does the expiring date mean anyway? For instance five years and now you lubricate a watch if you are in a commercial business you might is still more work watch would go out for may be another five years or so?

I think Moebius starting putting expiration dates about 15 years ago, before that there were none. It's been discussed quite a bit, and from what I gather it is really zero issue to use expired oil. I think mainly it is because bottles get opened dozens of times to refill oil cups and this leads to contamination and oxidation of the oil; sealed and or infrequently messed with it's good for ages.

 

I have some Kluber P125 here and it doesn't have a date, in fact it isn't even marked Kluber, just a Horotec number. I think they buy it and repackage it. I don't think it "expires"; I use Kluber greases on other things and never saw any literature about it expiring, just about its working life in use.

@JohnR725, could you please try to rephrase that question? I'm afraid I I don't understand it. Thanks!

OK, I'm getting myself some Kluber. Although my wallet will cry, I'm hopeful my automatic barrels will forever more rejoice!  Thanks!

so what I'm saying is purchase a horological lubrication it has a expire by date which basically means use within this time span. So purchase a lubrication that says it's good for five years at  basically five years you lubricate a watch now how long is the lubrication supposed to last? We don't actually get a how long does it last in the watch date. Obviously if it has a five-year shelf life and you lubricate a watch and let's just make a guess the watch will last five years out to the field then maybe we just multiply all those dates by two. So basically the lubrication now has a 10 year life. then it's a modern synthetic oil shouldn't have anything to break down hopefully and maybe in real life it's good for three times its life you wouldn't want your watches all disintegrate exactly 5 years from the last day of your oil expiring would you? So basically I'm saying is all the lubrication's at least the synthetic ones should have a really really long life.

That is unless you're running a commercial shop you getting paid for your watches then you can afford to replace all your lubricants every whatever number of years it's part of doing business.
