# Timefactors Smiths Navigator PRS-48 Full Set The Smiths Navigator is a faithful revival of the IWC Mk 11 of the famed Dirty Dozen, using the original Air Ministry specification but with higher anti-magnetic properties (20,000A/m) and sapphire crystal These watches sell out on [Timefactors.com](http://Timefactors.com) the second they release them. Also, if you're in the US you now have to deal with tariffs when purchasing new... **Case** • 316L stainless steel, brushed finish with polished bezel • Diameter 36mm • Lug to lug height 46.4mm • Thickness 11.3mm to top of the crystal • Lug spacing 18mm • Anti-magnetic 20000 A/m • WR 10ATM/100 metres/330 feet • 77 grammes with strap • Full anti-magnetic cage, screw back, drilled lugs This version comes on a strap with deployant, which I immediately swapped out in favor of a supple buffalo leather strap from Fluke. The watch looks great on both. Check the album for a picture which includes what it looks like on the gorgeous blue buffalo leather strap I got from Fluco.
