Lubricating rotor?

[Robinos]

Hello, I recently bought an GMF daydate with the movement Asian ETA 2836-2 and when the rotor spins it sounds "dry" or some metal against metal, so I decided that I am gonna silence my rotor myself, just take off the caseback and remove 1 screw, BUT im not sure about what type of lube to use... after doing some research I think I found out whats best for the rotor but im not sure so thats why im here, is this recommended to use on the rotor and jewels? https://www.amazon.co.uk/gp/product/B003JIIN9U/ref=ox_sc_act_image_1?smid=A25F817DGV5HJC&psc=1

I am also ordering this set to remove my caseback on my daydate. Assuming it fits.

Any feedback is appreciated thank you.

Also I am aware that there is cheaper alternatives but I need something that can stand really cold weather without freezing, cause I live in Norway and here it gets too around -40 celsius at worst.

Moebius 9010 or 9020 - do NOT cheap out on this. Some watches might get upset if you run them that cold though but it certainly won’t damage anything. I would recommend 9010 if it will be cold for most of its life. If you spend most your time inside, either is fine. Do some research on your own too as I’m not an expert.

Moebius 9010 is a bit too light of a oil to use on rotor bearings. I’m not sure what the ETA service manual calls for, but I’d strongly suggest using HP1300 or D-5 instead. These are both still oils (not grease) but are heavier (thicker) so will be less likely to spread / spray out as the rotor moves and cause problems in other parts of the movement.

You may also want to remove the rotor first and clean it in 99.9% isopropyl alcohol to be sure that there’s no old oil or dirt in the bearings or races before you add new lubricant. Also, don’t over do it with the lube. A little goes a long way. Buy some cheap oilers or use a pin to apply as little as possible to each ball, then spin the rotor to see if it moves nicely.

Sorry mobile won’t let me edit - that exact set is wonderful, i have it, but you need to have a LOT of pressure downwards or you will quickly strip the splines on the caseback. Dont treat it lightly. Make sure the watch is SOLIDLY in some sort of appropriate plastic jawed vice when you do this.
When you get the set for the first time, try using one by hand very lightly on the caseback to get a feel for how easily it slips without damaging anything.

Also, it’s unlikely that the oil will ever actually get to -40C if the watch is on your wrist. Your body is +37C and the watch caseback is metal and will happily wick away your body heat.

Edit: here's a wrist roll from a cold sunrise (air temp was probably around -20C) after camping on the Bishop Glacier in winter. No problem with D-5 lubrication of the rotor on my CF Daytona.

Any thoughts on Moebius 8000 on Amazon for $12 shipped?

Moebius 8000 is non-synthetic (so it will not last as long), and it is a less viscous oil than 9010 (that is, you're going in the wrong direction, you want more viscous). I would strongly suggest you go for HP1300. It's not that much more expensive, and it's exactly what you need:

Moebius 9104 Synt-HP 1300 Synthetic Watch Oil 2ml

The Moebius HP high pressure synthetic oil line is available in 4 viscosities. This version, the SYNT-HP 1300 9104 has a viscosity rating of 1261 cst and is a very high quality oil for mechanical and chronograph watches. 2ml bottle, Swiss made.

I'd say D-5 is better for rotors, but HP1300 would be better in his climate.

REMEMBER, JUST A LITTLE DROP. You can buy a watch oiler from bergeon for $9 off Amazon. Little teeny tiny drop.

Exactly this @littledomo that 2ml bottle of oil will last you forever. You just need to add a tiny amount with a pin or an oiler (basically a pin with a slightly flat head).

Yep and these oils are viscous, so it should be easy to spread that little drop around with a pin, you can move the little bead around and such, it's not like water. Just did two of my watches today.
