Love the style of these Railroad watches Gary !!! bounce Just like the Ball model there is that terrific mix of
bold black numbering, markers, and hands with vibrant red, and white ! Can't believe the fantastic hands,
and how cool it is that Bulova worked with Longines like that too ! Outstanding as always sir !!!


Haven't worn this Citizen in a while here...

Technically Bulova licenced the design to ETA/ESA, then they supplied variants to most of the the Swiss companies.

They appeared in Omega f300 and Megasonic, Longines Ultronic, Tissot Tissonics, Zenith Electronic, Baume and Mercier Tronosonic, Certina Certronic, Titus Tuning Fork, and Etena Sonic.

Also Citizen and Universal Geneve had their own licence with Bulova and made their own variant rather than use the ETA/ESA version.

I have an f300, Titus, Longines, and Eterna version, but only the Longines works. Service is expensive on these and I would rather not pay a huge amount of cash to get them running.
