Here's a 1960s Birks single button chronograph in excellent condition.
Check out the military-style dial, parchment white with light, even patina...and those awesomely huge subdials and blued, lumed hands.
Cool beyond words.
This is a solid stainless steel case in classic dimensions: 36mm excluding the unsigned crown, by 43mm from lug to beefy lug.
Under the hood, a Venus caliber 1057 chrono movement, keeping excellent time. All pusher functions work perfectly.
Looks and feels like the Abercrombie and Fitch Seafarer...Birks is a Canadian high-end jeweler, along the lines of a Tiffany, FYI.
