I just got mine in metal bracelet. It is huge. The largest wrist watch I ever wore but loving it very much. Now this replaced my Tag Heuer Link calibre 16 chronograph.
Rosh FooCo Watches & Things indeed it is! Only Speedmaster I’ve ever had was a Mk II vintage on bracelet (1970) which I foolishly sold and now can only wish for one as tines are hard
I have the Hyakuichi 101 hyaku1-003-WH, not quite the same but a far more affordable US$125 homage direct from Japan. I love that watch & it's always in rotation even though I suspect the company might be involved (wittingly or not) with replicas.
I hope those measurement callipers have non-metal guides, the clumsy way you measured and making contact with the case made me wince uncomfortably, look after that beauty and take better car man.
Thanks for your concern! You'll be glad to know that all is well and the Speedy is tough enough to deal with the very finest plastic-headed calipers the world can throw at it! 👍⌚️
