The "big eye" refers to the minute register being considerably bigger than the second register, with the minute-register hand being oversized with a distinct circle. I've taken closeup pictures of the dial at extreme proximity so you can see the detail and any blemishes. The case is exactly that of the 60's Heuer Carrera: 37mm (40mm with crown) by 45mm.The Valjoux 7733 is the Heuer Carrera movement. The case appears solid stainless steel (despite caseback saying steel back) with zero tarnish or brassing. The movement works great, as you can see in this video, I recorded just now. Please consider this is a vintage timepiece so I cannot guarantee it will not need a tuneup to run properly when you receive it.
