Note the improved bezel pearl on the insert. Many topewatch.com/sea-dweller_rolex-watches.htmlreplica Seadweller and Submariners have horribly inaccurate bezel pearls and bezel inserts in general. This has been largely corrected. Also the bezel itself is thicker on a Seadweller than the Submariner. Many replicas just use the Submariner’s bezel which in the past was also an easy way to spot these watches as fake.
