If price is the constraint, the IWC Schaffhausen Iw328801 Aquatimer Automatic at $6,700 (vs $21,600 for the Fifty Fathoms 70th Anniversary Act 1 Series I) covers most of the same brief. From the independents, the Elliot Brown HOLTON AUTOMATIC: 101-A10 is the standout microbrand take — pro diver and Looks nearly identical. Stepping up, the Patek Philippe Aquanaut 5968 ($61,766) is where the same idea goes with a bigger budget.
