TECHNICAL GUIDE

 

DATE SETTING FOR YOUR VINTAGE OMEGA:

• Caliber 353 and 355 – There is no quick set feature on these very early calendar calibers. 

The date will advance by turning the hands every 24 hrs. 

The date can be set forward or backward depending on the direction in the hands are turn.  

Turning the hands clockwise will allow you to set the date forward. 

Turning the hands counter clockwise will allow you to set the date backward. 

For instance, if the date is ahead by a few days, it is better to counter clockwise turn the hands. 

• Caliber 502, 503, and 504 – There are two ways to set the date for the following calibers. 

You can set the date by turning the watch hands every 24 hrs for each date to advance. 

Or, you can turn the hands until the date changes and then counter clock turn the hands to around 11pm. 

From here, turn the hands back to 12 midnight, and the date will change once more. 

Keep doing this until you get to the correct date before setting the time. 

• Caliber 560, 561, 562, 610, and 611 – There are also two ways to set the date for the following calibers.  

You can set the date by turning the watch hands every 24 hrs for each date to advance. 

Or, you can turn the hands until the date changes and then counter clock turn the hands to around 9pm. 

From here, turn the hands back to 12 midnight, and the date will change once more. 

Keep doing this until you get to the correct date before setting the time. 

 • Caliber 563, 564, 565, 750, 751, 752, and 613 – These are calibers with quick set date features.

The quick set is activated each time you pull the crown out to the second position.  You will need to pull

and push back the crown for each date to advance once.  Please avoid using this quick set date feature when the time

is around 10 pm to 2 am.  This is to prevent the quick set date corrector from interfering with the regular 

driving wheel.

 

BEFORE WEARING YOUR AUTOMATIC WATCH:

Before wearing your automatic watch for the first time or if you have it resting for over a day, it is best to give it an initial wind before wearing it. 

The initial wind consists of 15 times hand wind to the crown, giving the watch a boost start.  If you’re someone who has an inactive occupation

(ex. Working on the computer) throughout the day, you may need to hand wind the watch now and then to keep it running strong and accurate. 

 

IS MY WATCH WATERPROOF?

The term "waterproof" has been replaced with "water resistant" as it was very misleading.
People assumed their watch could do anything underwater or go to any depth. In watch terminology, the meter depth is measured differently than what it says. Vintage watches are considered to have 30m water resistance, which means the watch cannot be submerged in water or showered. Washing your hands or out in the rain will not harm your vintage watch.
