Focusing in on the watch for a moment, there's been some kerfuffle https://www.luksuszegarki.pl/luksus-produktu/omega/ as to what reference GMT-Master Magnum wore. For years, word on the street was a 1675 – the classic matte dial variant produced from 1959 to 1980. With a bit of investigation and some direction on where to look, https://www.uhren-replik.de/produkt-Sammlungen/tudor/ we can say with confidence that it was in fact a reference 16750. This was the successor model to the 1675, produced from 1980 to 1988 – matching the https://www.goedkopeluxehorloges.com/luxe-categorie/iwc/ series' run to the very year. Coincidence? (Well, probably).
