Over the (many) years I had some Rolexes (Sub/LN GMT Ceramic Deep Sea, SS Daytona), some IWC(Portofino, Fliegerchrono, Doppelchrono, Big Inge twice, Vintage Inge, BP 5004), some Zenith El Primero, Girard Perregaux F300, a few JLC(Polaris ltd, Compressor Chrono, Navy Seals Alarm) , a few Omegas 2500 PO, Panerai 320, a '69 Breitling Chronomatic, Avenger Seawolf , AP RO SS and ROO SS rubberclad(nice brand but way overpriced!), and now a Navitimer 01 Limited steel/croco. Runs very very accurate. The best besides the Rolex 16610/116610 I had.
+ 0.2 s /24h or stays within 0/0 24h...for a week. amazing for a mech watch.
I'm in the watchbusiness btw.
