Dan makes a very good point here. I agree that we are seeing more sales of watch heads only of late. In some ways that's a good thing, as I have had watches that have been put on the cheapest new strap possible and I have probably been charged a premium as a result of the watch having a new strap, even if it was one that I would be changing immediately on receipt. (Or maybe I'm just smarting as I've used up my stock of straps and buckles!).
It was great that the seller of my smoke-dialled barrel Carrera included the original bracelet as well as the strap it was on - it made it even more of a bargain, and I'm still a little surprised (but thankful) that it wasn't sold seperately...
So maybe we have a little section in the price guide where we try to give ballpark values for the accessories (maybe because I'm in Berlin right now, but I want to use the German equivalent "Zubehör" instead of "accessories"; roughly, "things that belong to the watch", which is a reaslly nice way of putting it)? Bracelets, buckles, papers, boxes etc.
