Lemania CH27 the movement that went to the moon!

P1150126It’s well known fact the Omega Speed master was the official watch that went to the moon. But Lemania was the company that made the 321 for Omega and is almost identical to Lemania’s own chronograph movement, 2510, which is a later name for their calibre 27CH-12. This Lemania CH27, sent in by a client, has the lowest production number I have ever seen. It’s not running and has a broken stem.

P1150129

Movement looks nice! Serial no 132!!!

P1150130

I remove the hands and dial.

P1150132

Once out of the case the movement starts ticking, but the balance is very wonky and needs closer inspection.

P1150133

Hmm that looks a little crooked…

P1150135

Whaaaat!!! The upper and lower balance staff pivots have literally been glued in place to repair a broken staff. I applaud the attempt, but they did not do a good job… I think replacing the staff will be the way to go.

P1150137

I start taking the movement apart.

P1150138

Down to the base movement.

P1150139

Down to the gear train layout.

P1150254

The lower balance jewel is broken and will be replaced.

P1150134

The upper cap jewel is also cracked and will be replaced.

P1150255

Here I’m riveting a new balance staff in place. Correct balance staff is Ronda 2789

P1150256

I fit the roller to the balance.

P1150257

Balance is placed back into the movement for cleaning.

P1150269

Movement cleaned and ready to be put back together.

P1150268

The balance is no longer wonky and swinging freely.

P1150271

Fit a new mainspring.

P1150275

Base movement back together and ticking.

P1150274

Watch is preforming like a dream!

P1150280

I start putting the chronograph layer together. The stem and crown are borrowed from one of my own projects.

P1150281

Setting/winding mechanism back together.

P1150282

Movement goes back into the case.

Another shot of the legendary movement!

Only thing wrong with this watch is that it’s not mine! 😉

    Wow! That’s one hell of a find, and the condition is stellar – perfectly aged, looks like gentle(ish) use, and hasn’t been hacked at (albeit bodged, yikes) on the movement side of things… much-want!!
