I had several Twist-O-Flex bands way back when. Comfortable, attractive, and they didn't pinch like most expandable bands.
This version is available in 38and 42mm, in a brushed stainless finish.
Maybe these will become available in other versions— polished stainless, brushed and polished black, if they catch on.
I have no idea of the present day quality. They may fall under the 'They don't make them like they used to' bus.
No silver Watch yet but I'll grab a band anyway, if only for the nostalgia.
I really think that from an aesthetic point, a link band looks better on the Stainless or Stainless Black Watches. But I'd get one if it were available in matte black.
