Yes that's true that the oils is a bit pricey if buying them all together.
However the shelf life is a bit longer for most of them around 5 years and it's calculated like this: if using a 5 year old oil it should still last another 3 years applied in a movement before the properties are outside the tolerances.
Also I would say that the smallest available size of each bottle will still be enough to service approximately 5000 or more movements. My last batch of oils that expired in 17/18, around 2/3 of the oils went down in the chemical waste recycling bin.
Also I would not recommend it but the HP1300 oil can be used instead of the blue grease on most friction parts from keyless to other parts where the force is a bit higher. The grease is much more easy to work with and apply the oil tend to run away and go where it shouldn't if not oiling very precise on the right spot with the right amount. It's like using Epilame on escapement wheel and the Pallet fork and let them run 30-60 min dry before oiling the escapement it's much easier and the result is 10 times better than without epilame. This is of course from my professional view.
Last all the clones from VSF both the Gmt and those without Gmt is the same regardless of which caliber no on the rotor. The Gmt just have a extra gear under the dial.
i still have to check the reversing wheels. Have been busy with non watch related stuff lately. However I will soon have another VSF clone for service then I will check, probably early-middle of April.
