If you are based in the UK, you can try
http://www.watchbattery.co.uk/shop/Timex_Watch_Straps.shtml
for genuine Timex watch straps. Most will be attached to the watch using a spring bar. The site's help page gives you some help on replacing a watch strap and you can also get a spring bar removal tool from there too.
