Omega watches have been influential in the watchmaking world since 1848 with their precision and mechanical details. The Omega Seamaster Automatic collection of watches feature self-winding movement, precision and durability. These watches also show the date and have a transparent case back. The crystal of these watches is domed, scratch-resistant and made of anti-reflective sapphire crystal. The date and time settings are the same for most of the Omega watches. Setting an Omega Seamaster Automatic watch is quite simple as long as you follow directions carefully.

Locate the knob on the side of the watch, which can be set into three different positions by being pulled out. The original position is known as the first position. Pull out the knob to the second position. You will hear a slight click.

Turn the knob forwards or backwards to set the date. The hour hand will move in one-hour jumps. The date changes by a day either forwards or backwards every time you pass midnight. Turn it until desired time is reached. Then push knob back to the first position, or to the third position to set the time.

Set the knob at the third position and check to see if the second hand stopped. Turn the crown forwards or backwards to set desired time. Pay attention to the date, which may change if you pass midnight. By passing midnight, you will be able to distinguish between a.m. and p.m. time. For example, to set the time at 7 p.m. rather than 7 a.m., turn the knob forward until the minute hand passes 12 and the date changes. Then, turn it backwards to 7, and you'll know for sure that this is 7 p.m.

Check the hours, minutes and seconds as well as the date. If everything is correct, push the knob back to its original position. The date and time are now set on your Omega Seamaster Automatic watch.
