A very unusual mid-century Avia with one of rarest complications you can find in a vintage watch: a big date. At first glance it reads as a classic Swiss dress watch, but the oversized two-disc date display at 12 immediately gives it a completely different personality. It belongs to a small, overlooked family of vintage big-date watches powered by the Venus 220/221 calibre family. These movements are genuinely scarce, and that examples like this do not surface often. The chrome-plated case shows visible wear, which is entirely expected on these watches and honest to the period, while the stainless steel caseback provides better long-term durability where it matters most.
