How to wind, set the date, and use the chronograph on a 300M Omega just like this.
Now here's the thing, this is a ceramic bezel Omega 300M, this is not the previous generation
with the painted aluminum bezel insert.
There's a significant difference because this is the 212 series of this particular chronograph.
This is from the mid, let's say 2016 on up to the current date.
Now, this is extremely important, because this watch has some different features that
you should know about that are different from the standard 300M.
First of all, when you go to set the time, if you'll notice that this watch is on the
19th.
Now, whenever you unscrew the crown you're in and it pops out, one click and you're in
the winding position right away.
This watch has a very deep power reserve.
You want to wind this watch
however you choose to wind it - whether you roll it along your finger like this, or whether
you pinch it and roll it like this, you want to do this about 65 times.
The reason is because, each time you turn this crown, and as I've displayed in other
videos, you may think that when you do this, you're turning into full turn.
You may not be.
You may only be turning it a half turn, the three quarters of a turn, so 65 turns, as
you can imagine, will help get closer to the original 30 to 40 turns that would actually
require to power this watch.
Now, having said that, we want to make sure that that date is always respected in terms
of where the hour hand is on the watch.
We want to pull this out one click.
There's only one click on this watch.
There's not two because you cannot adjust the date through the crown.
We're going to go up and see if we pass 12.
If it goes to the 19th to the 20th, it does not, so that was noon.
I'm gonna go ahead and wind this watch around so that you can see the date change from the
19th to the 20th, and you see where it changed, that means it was midnight.
Now, in order to change that date, we want to make sure it's in the safety zone, regardless
of any other specification of Omega or any other watch.
I always just make sure that the hour hands in the safety zone and the bottom half of
the dial.
Now in this particular case, we want to push the crown back in.
It's not necessary, but you can.
I'm going to use a tool of some sort to push, because this watch changes the date through
the center crown on the helium escape valve.
You can use a pin.
You can use a soft tool.
It doesn't really matter.
It's up to you how you want to display this, but if you push this crown here, you'll see
it moves in and you'll hear the click for the date and you can actually physically see
it's now on the 21st.
Push it one more time, you see that positive change on the 22nd, the 23rd and so on.
That's how you change the date on this watch.
Now that is irrespective of whether or not this helium escape valve is screwed down or
opened.
Now, if you open the helium escape valve, this is for decompression chambers for deep
divers.
This is not necessary for the average individual, so you don't want to have this open any time,
for any reason.
It does have a reverse conical shape on it to keep water from getting in, but for safety's
sake, always keep it tied down against - screwed down against the body of the watch for water
tightness.
Now, once you set the date, you can go ahead and set your time to whatever time you wish.
Set it to two, push the crown in, push it in and turn it towards the 12.
Push it in and turn it towards 12th.
That's how you get it to lock down.
Once you push it in, it'll grab the threads.
Keep turning until it's locked down.
When it's locked down, you're good.
Now let's talk about the chronograph.
Here's how the chronograph works.
This is the start-stop.
This is the reset.
You can see that the chronograph's currently moving so I can push this button and it'll
stop.
Now, I'm going to punch this and reset the watch.
You see how the red hand reset to the 12 position.
Now, if you want to start the chronograph again,
you can go ahead and watch that chronograph move.
Now, this is the seconds hand for the actual watch itself.
This one will be in constant motion.
This red hand should not be in constant motion while you're wearing this watch, it runs down
the power reserve feature.
You might find that you don't get anywhere near as long out of the watch before you have
to physically manually wind it again.
You do want to pay attention to that.
This is a really great watch.
It's become one of my favorites throughout time.
Now the interesting thing is this is the minutes collector.
This is the hours collector.
This watch has to have this hand go around this dial twice.
Then this moves over one hour and so on and so forth.
I'm gonna go ahead and start, stop, and reset.
Every two weeks or so, when you've set this watch down overnight and you pick it back
up to wear it, you may not be generating enough activity throughout the day to fully rewind
this watch.
Every two weeks or so, pick it up, rewind it about 30 times here to keep the power reserve
full.
