I love mine, its an earlier E56061. You can see a few subtle differences from yours.
I picked it up on this very forum. They are definitely unlike most other watches, due to them being so light and slim. They do feel bullet proof though.
Any idea how you date these? I cant seem to find a reilable source.
Good to hear Brietling were ok. I dont know the last time mine had a battery or a service so it may need to go back to BUK at some point.
