tiny amounts of light oil.

Too much or too thick is bad.

Did they have any lube ?

I thought they ran in Jewel Bearings that run dry ? Normally these are cleaned with lighter fluid or similar that dries without residue.

Most lubes with change viscosity (and drag) with temperature.

Think, traditionally supposed to use graphite powder, as oil gums up this might do https://www.amazon.co.uk/Kasp-K30050-Gr ... 0912&psc=1

It does seem from Ronnie's post, oil is used, on 'through frame' bearings, but if you find any that are a Jewel Bearing, as it may have a mix of both, they need to be dry and clean.

I just now found this on Jewel Bearings;-

When I was a joung Craftsman I used to repair wristwatches, known as 'the dirty dozen' or primary makers such as Omega (the Rolls Royces), Eterna, Jaeger-le-Coutre, Vertex, Longines (tough and reliable) Buren etc etc and we did oil the bearings/balance staffs etc etc. But, alas, the oil came in thin sachets so I don't know of the trade names. I used to dip a hair into the oil and withdraw it very quickly so that a tiny glob remained on the end of the hair. That was all that was used on each end of the balance staff or wheel.

Remember that even with jewelled bearings, it's still a steel shaft rotating on and within a jewel cup (or cage) and in the case of the balance and escape (the tick-tok part of the train in your old mechanical movements)), the axle is rotating to and fro many times a second.

There......., that takes me back

If the clock has jewel bearings, they do tend to run dry.

Lower grade movements will use hardened steel spindles running in brass bushes. These do need lubrication, but only a tiny amount.

If you watch "The Repair Shop" on BBC 2, you'll often se Steve Fletcher mending clocks.

He often remakes bearings and on reassembly, dots oil on using the tip of a jewellers screwdriver.
