I also have this watch in black as well as white. Along with 4 other Ball watches, they are the Trainmaster Roman with bracelet, Trainmaster 135th anniversary, Roadmaster GMT and Engineer M marvelight. Get a Ball watch, you won't be disappointed.
I love my Fireman Enterprise. It gets so much wear time I've actually become a one watch guy! But wait a second here yours has a domed sapphire?? That must be a newer edition.
