Hello all, just took delivery of a pre-owned gen TT1 Worldtimer. It's an awesome watch and something of a rarity it would seem, but the only thing I am not loving is the single-domed crystal. I hate single domes because of the magnifying/distorting effect they create plus the increased reflections. Pretty poor show all round. So I want to fit an aftermarket double AR, double-domed crystal but where do I start? I wager this watch has not been repped, which I wager would make actually figuring out the exact required dimensions of the crystal rather difficult. Any advice much appreciated, thanks a lot.
