I have two 38 mm Weekender faces from over a dozen years ago. No clue what strap to use. Anyone know of somewhere to buy 38 mm straps?

Every strap I see on Amazon is listed as 20 mm. Since the watch faces are 38 mm, I assume those 20’s won’t work. Does anyone know where I can find the correct size straps? I’m assuming mine got lost in one of the several moves I’ve made over the years.
