Production year was1968. Fifty two years old and running perfect.

On average they were pretty good. Not many are still around today. I have one similar to yours from 12 or 15 years ago with a swisseta 2836/Asian 24 hour mod. There were a few different models made depending on the basic case used...submariner, 1655 etc. Watches with dials that have 'Oys Perp Date' and 28800 bph movements are closer to a 16750 than a 1675. The 1675 did not have OP 'Date'...OP only and ran at a lower beat rate...18000 or 19800 bph. Mine has 'OP Date' and 28800 beat rate so it leans toward a 16750. Some common faults seen on the various 1675/16750 replicas that were offered: Crowns are usually 6.0mm instead of correct 5.3mm. (relatively minor imho) Crown guards are too narrow. (minor, not many will notice...except on RWG) Bracelets should have regular clasps, no flip locks. Regular oyster or jubilee bracelets are Ok. Should have hollow mid links on oyster bracelets, not solid. (minor) Some replica bezels have click notches, genuine 1675 and 16750 do not. (minor) Some replicas had MG crystals instead of acrylic. (major fault, usually hard to fix) The 1675 and 16750 should have non adjustable 24H hands, not adjustable 24H hands like on later models. (minor) GMT time should be kept the same as 12 hour time if 24H hand is adjustable. (minor) Some replicas have 'blind' spring bar holes in the lugs. (major flaw, hard to fix) Most will need the spring bar holes drilled out. (easy fix if they are through and through, not so easy if blind) Etc, etc. Earlier genuine 16750 came with painted hour markers. Later models had applied markers. Applied markers are cool imho...same goes for the 5513. They look more 'vintage'. Genuine 1675 and 16570 cases look alike, genuine crystals, case tubes, crowns, and bezel assemblies/inserts are the same. The 16750 replicas were also sold as 1675, and 1675 as 16750. Most were the same watch.

Welcome back dadog and WM! It’s good to see you. Dog, believe it or not I finally succumbed to the siren song of the Panerai and bought a few. My, they’re .................. large.

Ah - to work on these particular watches you need to take a slow, deep breath.....of Heliox Helium Oxygen mix. 🤿

How about this one? A closed factory case with a gen 2230 (non -AC dial) and a PO bezel and insert. Built by @SSTEEL
