31 Jewels
Hello guys and girls
For a long time I was wondering why Rolex listed their amount of jewels at 31 for all their Oyster models (with the exception of the Daytona and YMII)...
For those that never thought of it; for example, an Airking without a date, and a GMT-Master II with a date, and dual time zone capabilities are both listed at 31 jewels, eventhough the second one should have more jewels, since there are more gears inside the watch.
I finally made the phonecall to Rolex, and received this answer: The jewel count is based on the amount of jewels that are under constant force.
Meaning the ones for time keeping. The date mechanism is only in motion every 24 hours, so doesn't receive constant friction.
We can safely know that all their movements are fully jeweled, and most of them have more than 31 jewels.
Hope this answers the question I know I few of you had wondered!
