I wear them all the time and they often get immersed in water, banged and scratched and generally worn out! I buy them for $10 from the local Big W/K Mart but its not the watch itself that gives up the ghost. Its usually the watch strap that breaks.
Its very frustrating to have a collection of watch face's - albeit a little dinged - but not be able to wear them. I went through a phase of buying new watch straps for them and ran into that old age problem of the strap being more expensive to replace than the whole watch...?! The cheapest watch strap I could find was $12 and it lasted about two months.
I did go and buy a proper leather strap for $25 and reckon I might have got an extra three or four months out of it...
Its been an ongoing problem for me for a while now and I think I have finally I solved it!
Here's what I did...
Green-ness: 5/5 for not supporting Big Industry with the planned obsolesce of cheap manufacturing for ever!
Frugal-ness: 5/5 for being able to replace up to 5 watch straps for $2 with the same purchase of elastic
Time cost: Probably about 20 minutes from who to go
Skill level: Just knotting (lots of internet instructions for knots if you want to be fancy!)
Fun -ness: great fun to fix my watch for an inth of the cost of replacement!
