Leather straps
OMEGA recommends that you follow the steps below in order 
to preserve the condition of your leather strap for as long as 
 
possible:
–  avoid contact with water and dampness to prevent discolouration 
and deformation.
–  avoid prolonged exposure to sunlight to prevent the colour from 
fading.
–  do not forget that leather is permeable! Therefore avoid contact 
with greasy substances and cosmetic products.
–  if you have a problem with your leather strap, please contact your 
nearest OMEGA retailer!
Anti-reflective treatment

Introduction
Introduction
 
The anti-reflective treatment on both sides of the sapphire crystal 
improves the visibility of your watch’s dial. Wear and tear may cause 
marks to appear. These are considered normal and are therefore not 
covered by the warranty.
Screw-down crown
1 Introduction
 
Some watches are fitted with a screw-down crown which must be 
unscrewed to alter the date and time. After use, push the crown into 
position 1 then press and screw the crown back down, failure to screw 
the crown down will compromise water-resistance.
