Why do these watches include boxes?

Fitted presentation boxes served as the original retail packaging provided by jewellers and manufacturers at the point of sale. They protected the timepiece during transport and served as storage units for the owner. Surviving boxes often bear the name of the original retailer on the interior silk lining, adding local provenance to the watch itself.

How do I identify the decade?

Decades are determined through serial numbers stamped on the movement or case back, alongside stylistic cues in the dial typography and case geometry. Art Deco pieces show geometric symmetry, whereas mid-century examples lean towards minimalist or rounded profiles. Documents and original papers, when included, provide exact production dates that corroborate the hallmarks.

Are these watches mechanical?

The timepieces listed from these periods rely entirely on springs, gears, and escapements rather than electronic quartz circuits. They require regular manual winding or automatic wrist movement to maintain operation. Master watchmakers assembled these intricate components by hand, resulting in sweeping second hands and visible internal mechanics.
