Price is surprising! but not really!
Update 5/29/2026 Hour hand has moved off course and the band broke. I got what I paid for. So far it operates as good as any watch I own! The leather band is a higher grade leather than I anticipated. It's a bit larger than I calculated but overall I like the looks and durability seems to be good.

Watch with day & date
Nice watch, light in weight. Looks good with the grey background. Has the day and date too, just wish they were a little larger, for easier reading.
