Rolex replaced the radium with tritium, and the above markings were used on the radium watches to indicate such. These watches are referred to by collectors as ”Swiss only”, as they only feature the Swiss text. Later on, Rolex changed to Superluminova, and now, Rolex has ”Swiss made” on all of its watches.
How do I know my Rolex is genuine?
Rolex watches include a serial number stamped between the watch lugs at the 6 o'clock position. You will need to remove the bracelet in order to find this. An authentic watch will have a deeply engraved serial number. You should be able to hold it to the light and see a slight glow around the edges.25 Apr 2019

Do I need to register my Rolex?
The first thing any new Rolex owner should do is register their new or second-hand Rolex in the RolexTracker.com global database. The numbers are engraved here by Rolex when the watch is produced. You may need the help of a jeweler to remove and replace the bracelet so you can access the serial number.17 May 2018
