I can't see how that would be cheaper as I help my local charity shops on a pro bono basis. But of more interest to me would be to understand how to work out the specification of a replacement balance given that the chance of being able to order the part from the company or OEM must be effectively zero..... -
It looks like after rolex someone serviced the barrel with P-125 chronogrease. Clean it up and you’ll be good to go… https://www.jewelerssupplies.com/chronogrease-p-125-420.008.html -
Haven't handled a Rolex in a long time but that's not natural. If the barrel is still useable then just grease as normal. -
Do you have the service manual for 3135 as it would explain the procedure then in the absence of that the current procedure for modern mainsprings would be breaking grease on the outer wall as it's an automatic watch. The mainsprings are considered prelubricated no lubrication is required. Then the arbor is lubricated with a suitable lubrication. Typically the only time you see well I haven't ever seen anything quite like that Rolex but Seiko watches often the barrel is filled with some sort of I believe graphite-based lubricant. Or if too much breaking grease was applied in it leaks out but that would be a heck of a lot of breaking grease. I wonder if the black would be molybdenum disulfide? There is a variation of 8200 Quite remember the number were a little bit of molybdenum disulfide Which is a really nice high-pressure powder is mixed in with the eighth 200 and maybe they applied a heaping quantity of that? -

The watch is from 1990 and was serviced just once around 20 years ago. No idea if the mainspring barrel was ever opened or changed before now.
