Hydro-modding. How hard can it be?

Is it really 'oil' in these watches, seems far too viscous.

Something like a refrigerant (CFC or similar) would seem far more suitable.

Oil viscosity seems the most likely culprit. For a digital it makes no difference. Or an analogue without a seconds hand, I suspect: the hour and minute hands moving so slowly so as not to meet much resistance.

But a quartz analogue watch has minimal torque, so I imagine viscosity is the issue. There were several different types of oil available in the shop, but only one 'silicon oil'. This is what others had used, so I thought I'd try it. But likely I need to research it a bit more. Posting the failure anyway in case useful to others.

At least the patient recovered. This watch has had a hard life.

There’s a chap over on the Christopher Ward Forum who posted the steps he took to modify his quartz watch. Here’s the link…

That's a very useful post. The same movement as mine too. So it must be possible. Reading it carefully, I think the main difference between how he approached it and my own efforts, is that he appears to know what he's doing. That often helps.

Superb thread. A good Sunday morning laugh and nothing irreversibly damaged, what's not to like?
A very Victorian approach to a problem, too
