FAQs

A bumper automatic movement features a weighted rotor that swings back and forth through a limited arc rather than rotating a full 360 degrees, using internal springs to rebound against bumpers.

Mid-century watches typically utilised stainless steel, gold or gold-plated cases, acrylic crystals, and genuine leather straps, combined with brass and steel internal mechanical components.

Authenticity is verified by inspecting the serial numbers and calibre markings stamped on the inside case back and movement, alongside the correct font styling on the dial.

A vintage dress watch pairs well with tailored formal or smart-casual attire, adding subtle historical elegance to a modern wardrobe.

Vintage mechanical watches require regular professional servicing every three to five years, protection from moisture, and careful manual winding if not worn daily.
