...at least to me. This is a Heuer Ref. 15013G owned by a UK collector. The watch was listed for sale on Chronotrader a while back and is an interesting design- has a similar "TV screen" crystal to the Silverstone, but otherwise it's an unusual look for a Heuer quartz model. In terms of size, it's quite contemporary- 35mm without the crown (43mm lug-to-lug) and 19mm lug width. If anyone knows more about the watch would love to hear more...it's actually quite a cool design, no?
