Moebius Synt-A-Lube 9010 Watch Oil This Moebius Oil is a general purpose synthetic watch oil, unequalled for pallet jewels, escapements, and balance staffs. It has been the watch industries leading synthetic oil for years because it is highly resistant to deterioration, it will not clog or thicken in the watch, and it prevents the small parts from getting gummed up in the movement. Once placed in the watch it will remain where you positioned it and last for years without spreading. Supplied in 2mL bottle. Viscosity rating 120 cST. at 20°C.
