Service: Breitling Navitimer 806 calibre 178

P1110306A good client has sent in his lovely 1959 Navitimer. It’s not keeping good time and needs a service.
P1110309

Lovely Venus 178.

P1110305

One would like a little better timekeeping than that!

P1110310

I remove the hands and dial.

P1110312

I start taking the movement apart.

P1110326

Down to the base movement.

P1110337

I now take apart the lower chronograph section. Look at all that dirt!

P1110342

Old mainspring.

P1110412

The movement has been cleaned. Now I see that the balance moves freely after fitting the cap jewels.

P1110411

I fit a new mainspring.

P1110413

Base movement coming together.

P1110416

Case movement back together and ticking.

P1110417

That’s more like it!

P1110418

I start fitting the chronograph components.

P1110420

Movement almost back together.

P1110424

Movement ready for dial and hands.

Movement back together looking great.

Great looking Breitling!

    Great post Mitka and lovely watch. Something that occurred to me as I’ve not seen a Venus movement with that plating finish before – is there any perceived wisdom about what finishes are better than others, Omega obviously used to go for rhodium…etc which I assume must be purely decorative rather than anything particularly functional?

    Wow, that’s amazing the reading you got on the timegraph after it all. Just goes to show a little tlc is sometimes all that is needed.
