Dial:

White porcelain dial in mint condition with Roman numerals black, with gold color hands. Dial has no chips or cracks and dose not been rebuild anyway. Dial 100% belong to that watch: has 2 square pins for fixing. Dial is fixing with 2 screws from board side of movement. It’s a pity to me that I forgot to make foto of back side of the dial, to make you sure that it 100% authentic. I didn’t know way it has Buttner mark but it has stamps on movement and case. Probably that watch “nominative”, made by special order. Unfortunately I found no information about Mr.Buttner.

Bracelet/strap:

Alligator leather watch strap

Lug width 20 mm
