To refurbish or not?

I have 3 Omega Geneve dynamic that belonged to my parents, 2 mens and one womans. The gold one seems to work ok and is in pretty good condition all in all. The stainless steel female one is again in good condition but the winder although intact doesn’t seem to work (changing time etc). The male stainless steel one is in poor condition - face degraded and a crack to the glass although it seems to work fine (see pics). My question is roughly how much would it cost to repair the female one and likewise refurbing the male one? Would it be worth it? I believe they are circa 1970’s, I remember my dad buying them when I was small. Any help much appreciated.

If you are looking for profit sell it as they are because in my opinion if you refurbish will cost more than you will earn selling after that..Regards.

Maybe the best solution for the last watch is to find a better dial on ebay..

Family items — I would just service so they work well and keep as is. But if you’re looking to sell, it’s not worth it (as has been said).
