If you intend to keep one as a souvenir, you would love the fact that both watches uses Miyota 2039 (Japanese Quartz Movement).
Battery is SR626SW, easily available and inexpensive.
In my opinion, the use of Miyota 2039 as the movement of this watch is a big deal… You know its going to last forever!
If you plan to use it daily (Robert Langdon look?)… The leather strap will not age gracefully… It uses a Tang buckle which causes the leather to chip. I highly recommend that you use a deployment buckle.
I keep both watches for my trips to Disneyland… Reminds me to be young at heart and to smile at little things…
