For dem der vil læse lidt mere om cal. 1441 er her lidt at hygge sig med:
Omega cal. 1441

Lige et lille uddrag:

Checking the rate
Check the rate in the following manner :
– Set the watch to exact time.
– Stock the watch for a duration of about 1 month.
– Check the watch by the same time reference which was used for the time setting.
– Calculate the rate M in sec/month.
If M > 0.8 sec/month, correct the rate.
If M < 0.8 sec/month, no need to correct the rate.

Correcting the rate
The watch possesses a manual regulation system:
See illustration
Going from « M » which represents the rate in seconds per month (s/m), we have to calculate the number of correction impulses «N».
M s/m = N rounded to the next full 0,33 s/m number
«N» has the same sign as «M» (+ or -)

Så blev vi da lidt klogere
