Omega Seamaster – Cal. 565

Hey there 🙂

Nick recently dropped off a few watches including this Omega Seamaster. When unscrewing the case back and having a quick look, I quickly realized this movement has never once been touched. The screws were brand new, not even the slightest mark. Cross referencing the serial number on the movement, this movement was made in the early 70’s. So, great buy Nick 🙂

Anyway, let’s get started.

After fully winding the movement, I put it on my timegrapher.

With the movement out of the case, with the dial and hands off.

I quickly turn the movement over and remove the automatic rotor off.

And again, I turn the movement over and start disassembling the calendar works.

Again, I turn the movement over to the bridge side and commence disassembling the crown, ratchet wheels along with the click.

Next, I remove the gear train bridge.

Clearly, I didn’t take any pictures of removing the barrel bridge and barrel. But 🙂 , I did turn the movement over again and start removing the keyless and motion works.

Here’s the barrel.

And, last but not least, time to start taking apart automatic rotor from the automatic bridge.

With the whole movement cleaned, it’s time to start putting everything together.

New mainspring.

I start off with installing the barrel and centre wheel.

Then, I install the gear train and both the gear train bridge and barrel bridges.

Followed by installing the ratchet and crown wheels along with the click.

And, the pallets and pallet cock.

Next, I turn the movement over and get started on the keyless and motion works.

Then, time to regulate the movement on the timegrapher. Pretty nice improvement.

Here’s a couple of pics with the automatic gear train installed.

And, time to install the dial and hands.

Last but not least, I install the movement into the case along with a new gasket.

As every watch I work on, I certainly enjoyed it. I hope you did!

Cheers
