Breitling Crosswind – ETA 7750

Breitling Crosswind – Cal. ETA 7750

Hey there,
today, I’ll be working on a Breitling Crosswind chronograph watch with an ETA 7750 movement. So, let’s get started 🙂

I finally had to give in and get a Breitling case back opener set.

Just a quick pic with the case back off and exposing the 7750.

With the movement out of the case, it’s time to start removing the hands and dial so I can get started taking apart the movement.

I use my Bergeon bezel tool to remove the bezel. Great tools, by the way.

With the bezel removed we can see this case needs a good cleaning and polishing.

The first thing I like to do is to remove the oscillating weight. Then, get started on the dial side.

Next, I turn the movement over and get started on disassembling the chronograph.

Getting there 🙂

Again, I turn the movement over and continue disassembling the calendar and motion works.

One more time, I turn the movement over and remove the main bridge.

Seems like I didn’t take more pictures. But here, the movement has been cleaned and organized. By the way, the new package you see in this picture is a new oscillating weight bolt, as the rotor is loose.

As usual, I oil the mainspring, treat the escape wheel, pallets with epilame, and coat the inner barrel wall with Kluber P-125 breaking grease.

Here’s the new bolt. Having the right tools to do the job always makes things easier.

Alrighty, time to start assembling everything. I start off with installing the gear train and barrel, as well as the balance hacking lever.

Then, I install the main bridge, pallets and pallet cock, ratchet and crown wheels.

I then turn the movement over and install the keyless works.

And again, I turn the movement over and get started on the chronograph components.

Next, I install the oscillating weight bridge.

And one more time again, I turn the movement over and get started on the motion and calendar works.

Followed by the calendar disc.

And dial and hands.

Then, I install the movement into the case and close it up.

Well, that was fun. Thank you for taking a look at my most recent job.

Cheers

Chris
