The Breitling Transocean Unitime Pilot (ref. MB0510U6/BC80/159M) is a sophisticated men's watch featuring a robust steel case and a striking black dial. While the case diameter isn't specified in this listing from Switzerland, the Transocean Unitime models typically have a substantial presence. This automatic timepiece boasts a world time function, allowing simultaneous reading of all 24 time zones. This pre-owned model is in very good condition and thankfully includes its original box and papers. New models of the Transocean Unitime Pilot, known for their blend of elegant design and global functionality, would also be available through Geneva Watch Company right here in Una, presented in flawless condition with the complete set. This Transocean embodies Breitling's heritage of creating high-precision instruments for travelers.
