Review of the Prometheus Recon 5

At least there's still no cyclops (date magnifier), and thankfully, they did not add polished center links like the new GMT Master 2.As with the Anniversary Submariner and new GMT Master 2, the Sea-Dweller DEEPSEA gets the new "maxi-dial" which means that the hour markers are larger, and both the the minute hand and the hour hands are slightly wider.The depth rating increases from silly to ludicrous: 1,220m (4,000ft) on the original to 3,900m (12,800ft) on the DEEPSEA.The crystal goes from flat thick sapphire to domed thick sapphire.New super-hard ceramic bezel with platinum-filled numbers. We first saw this design on the new GMT Master 2.Much-improved ratcheting clasp that increases in 1.8mm increments.They're calling the new model the Rolex Sea-Dweller DEEPSEA. The DEEPSEA has several changes from the original Sea-Dweller:As with the new Yacht-Master 2, it's more heavily branded. The previous Sea-Dweller was notable for its restraint; this one adds the "ROLEX" repeated around the chapter ring, additional blurbs on top of the "ringlock", and "DEEPSEA" above the center.The caseback goes from flat stainless steel to a titanium/steel alloy.The new "Ringlock System", which is a stainless steel ring under the crystal that absorbs some of the pressure.New blue-colored lume on the dial and bezel dot — very cool!.Larger case with slightly updating styling.As before, it has a helium escape valve, which only matters if you do saturation diving.
