Hi all! I recently acquired a Heuer Carrera 73453 --- my first vintage Heuer (am so excited). I had a question on the brushed finish of the case, as it's hard to tell from searching the web - is the original factory finish on the case meant to be vertical (brushed straight up and down) or a "Sunburst" brushed finish? Specs of my timepiece: * Heuer Carrera 73453 * Made: 1970 - 1971 * Serial: 258 1XX * Mechanical movement 7734 * "first execution" dial (single marker inserts), later "Tachy" ring (TACHY printed @ 1pm), "second execution" hands If anyone has the same watch (model / year etc), I would love to see some clear photos of the case please! Thanks in advance!
