Genuinely the best out there
Style: Trifold
Wow! I am so impressed with the quality and size of this wallet. I searched hard for a genuine leather trifold and this one exceeded expectations. My boyfriend loves it and I can tell it is going to hold up. After he started wearing it in, the smell of the leather really came out. Im very happy with this choice!

Nice classic design, love the solar
My husband is watch guy. From bulova to Tissot to Rolex. This one is nice basic addition, it has an easy to read, classic face. It’s solar so no matter or kinetics to worry about! It’s easy to charge (10 minutes in any light) and retains a charge easily. Good job Tissot.
