I searched the WWDB for a GMT in steel, smaller than 39mm
and surprise (not really) it's a Leman! 2160-1127-53 Nice design, sits perfect on my wrist, really natural implementation They really should bring Leman back if they want me back in the boutique ...

I have the X-71 bracelet version and it's my favortie travel watch, the one that stopped me from continually collecting more and more GMT and dual time zones.
