So I had the following items:
If the case increase in size keep it to no greater than 1mm in case back area. Must have the hesalite crystal and the solid case back. Agree on the column wheel 321 with the coaxial, Absolutely keep the case as is. Use the newer screw bracelet with the new micro adjust clasp (like the Mark II). Ceramic insert in the bezel with Liquid metal numerals. Would like to see the classic dial done with all the markings using the new laser etching they used on the 45th anniversary. Last I would like to see a Titanium case and bracelet option that retains the black/white dial and the black bezel insert.
