Good afternoon all,
As you may have seen I was finally reunited with my collection of watch books after a prolonged move. I was flipping through Wristwatches by Kahlert and came across these photos of the 3615. It's such a rare beast, with almost no Google image results, that I thought I'd share these quick iPhone scans of the movement. The extent of the black polish is truly exceptional. What a watch!!

Enjoy!
Cheers,
