when it comes to simple & brown leather - without any "fancy" stitching.
Matt finished aligator or even calf/pork - not too dark, not too light.
The added "warmth" should looks just perfect ...
Regular straps of today look (slightly) different most of the time, but I think it´s worth the hunting or going bespoke.
Example of a regular strap ...
Only minor differences to most ...
Too often I see outstanding watches with "ordinary" straps and I never will understand why people take so much attention to the watch only. Me always asking for more

Cheers,
