Även om Rolex är bra grejjer så är det väl fortfarande lite skillnad på en Sub och en specialbyggd RM (som även är sponsrad och därmed utan service och reparationskostnader för Nadals plånbok).
Jag ställde liknande fråga förra året: https://klocksnack.se/threads/hur-stora-skakningar-klarar-en-klocka.30047/
Ett tekniskt svar fanns på Omegas webbsida (som numera har försvunnit, http://www.omegawatches.com/press/press-kit-text/1122) där testkraven för Månklockan presenterades. Med andra ord, månklockan klarar av 40G.
1. High temperature
48 hours at a temperature of 160F (71C) followed by 30 minutes at 200F (93C). This under a pressure of 5.5 psia (0.35 atm) and relative humidity not exceeding 15%.
2. Low temperature
Four hours at a temperature of 0F (-18C).
3. Temperature-Pressure
Chamber pressure maximum of 1.47 x 10-5 psia (10-6 atm) with temperature raised to 160F (71C). The temperature shall then be lowered to 0F (-18C) in 45 minutes and raised again to 160F in 45 minutes. Fifteen more such cycles shall be completed.
4. Relative humidity
A total time of 240 hours at temperatures varying between 68F and 160F (20C and 71C) in a relative humidity of at least 95%. The steam used must have a pH value between 6.5 and 7.5.
5. Oxygen atmosphere
The test item shall be placed in an atmosphere of 100% oxygen at a pressure of 5.5 psia (0.35 atm) for 48 hours. Performance outside of specification, tolerance, visible burning, creation of toxic gases, obnoxious odours, or deterioration of seals or lubricants shall constitute failure to pass this test. The ambient temperature shall be maintained at 160F (71C).
6. Shock
Six shocks of 40 Gs, each 11 milliseconds in duration, in six different directions.
7. Acceleration
The equipment shall be accelerated linearly from 1 G to 7.25 Gs within 333 seconds, along an axis parallel to the longitudinal spacecraft axis.
8. Decompression
Ninety minutes in a vacuum of 1.47 x 10-5 (10-6 atm) at a temperature of 160F (71C) and 30 minutes at 200F (93C).
9. High pressure
The equipment to be subjected to a pressure of 23.5 psia (1.6 atm) for a minimum period of one hour.
10. Vibration
Three cycles of 30 minutes (lateral, horizontal, vertical), the frequency of varying from 5 to 2,000 cps and back to 5 cps in 15 minutes. Average acceleration per impulse must be at least 8.8 Gs.
11. Acoustic noise
130 db over a frequency range of 40 to 10,000 Hz, duration 30 minutes.
