Excellent value.
Color: Black
I wanted an inexpensive “work” watch so I could keep my “good” watches from getting beat up.
This one is an excellent choice…solar so no battery to replace. Bright light function for night time check. No analog function is the only downside for us old folks. Overall a bargain! 👍

Carharrt Quality
Color: Brown (Passcase)
I purchased this bifold wallet approximately about a month ago for my husband. It seems to have the trusted durable Carharrt quality, but it hasn’t been long enough to review its durability. It’s very nice looking. I gave it a four star due to he did find it stiff & tight fitting at first, it didn’t fit all that he had in his old wallet. I’m sure with time as with any leather it will soften.
