Original white porcelain (enamel) railroad dial with bold Arabic numerals and sunken sub-seconds dial — clean, no hairlines or chips. Blued steel "spade and whip" hands with uniform color, no rust. 

Movement features beautiful damaskeening and a swan-neck micrometric regulator. Crystal is clear. Includes matching gold-colored metal chain with swivel connector and spring-ring clasp. Movement is running.

Condition: Excellent overall. Case shows light surface scratches and a shallow indentation on the back cover, consistent with age, but no brassing-through. Dial is exceptionally clean. Watchmaker service marks ("Z-133") inside case back.
