How much is it worth

Will cost more to change the movement than its worth.....lose it.

no make model, year photo so not worth anything
take it to a pawn shop then double what they say

If you are interested to have some idea about how much are worth your unspecifies watches, go to ebay and look for similar models. might give you idea if worth or not to repair them
Please take note that an old watch, if not in good shape, faultless, has really no collectors value, just because it's old. There are too many old watches around. If has gold parts, only worth value of the gold. Goldfilled watches are not worth anything if they are not perfect.

That model does not come with diamonds therefore the diamonds are what's known as aftermarket. I can also tell from the photo that they are aftermarket because they did an awful job setting them in the watch. That watch in its original unaltered state is worth $200. With the aftermarket diamonds though I would say that your watch is worth between $75-$100. Believe it or not the addition of aftermarket parts even diamonds takes away from the value of a watch.

If it's a men's watch it is still worth around $100 - $120 depending of which model, so it's still worth changing the battery my friend.

The M8 indicates this watch was produced in 1968 and probably sold for 250-350,this is a tuning fork watch and they are highly collectible and worth up to twice the value of the gold or more depending on the model and condition

Raymond weil geneve tango 5560 stanless steel 5atm saphire crystal z447644 swiss made can u tell me about that modle? and how much does it worth?

the 3200 model was one of the sturdiest models Luminox has ever made...the crown is not too expensive to replace and unless the threads on the case tube are bad or there is water damage it would be worth repairing IMHO
