And then the gods brought the perlon straps. Attention: do not try to use this on a modern Carrera. Ask me how I know.
On the subject of budget straps, I've always liked the velcro Animal straps, infinitely adjustable, very tough, very cheap. The only downside is that with a layer of Velcro and a layer of webbing lifting the case off your wrist, a chunky watch can feel very clumsy. The one pictured started off as nubuc leather, but has polished with age. I ran my Quartz aquaracer on one of these for a while, but ironically the metal TAG strap is better for surfing as it fits under a wetsuit more easily. apologies if that's too far off topic!
Thanks for posting Hubert- I'm a big fan of these types of straps- Zulu, NATO, Perlon, Sailcloth, Velcro- all great ways of changing the look of your watch and not so expensive. Several of the new 2015 models will have different types of strap, which is a positive development. OK, I have to ask @elbeik ...what did you do to your Carrera
