This is a large watch at 43mm with multiple functions in the perpetual calendar. It has an automatic movement with 3 shock resistant features.

It is an insanely complicated watch that can read the day or date in the future.

It comes with a lovely blue dial that has an almost sunburst feature. A really nice looking dial. It comes with a new black rubber strap that sets of the dial very well.   It's in excellent condition and looks like it has hardly been used.   

Despite the watch having such complications inbuilt it is easy to read and easy to wear everyday.
