A friend of mine from UK located this piece and brought it back to me after CNY. TAG cross over with MB ended a few years ago, and this SLR watch has been on my "HAVE to GET" list. It housed a El Primero 36 Regulator movement and no other similar products...
Never seen this version before but there is also a more conventional SLR chrono, too. Not sure about the movement there but the pushers are interesting too - if not quite so special as with this one. Thanks for sharing!
