Here are a couple of Ebel 1911BTR chronographs, one with a caliber 137 and the a caliber 139:
The BTR's are newer versions of the Lemania-based caliber 137 movement. This one is older, with the classic Lemania-style rotor. It's an Ebel Type E from maybe a decade ago:
And now for something completely different. Here is the ST-19 movement display of a Seagull 1963 reissue. It's a new version of a Venus 175. It's not a copy--the Tianjin factory bought the movement and tooling from Venus fair and square:
And while we're in that vicinity, here's a vintage Dong Feng ("East Wind") from Tianjin before they started exporting under the Seagull brand. This is the ST-5 movement from prior to the use of Seagull Stripes--the first good movement entirely designed in China. One pic shows the original caseback, and the other a replacement display back:
Now, let's go smooth. These next three show Ebel watches with their classic smooth back. These are exceptionally comfortable watches. The last of these three is the Ebel one-piece case for which they are famous. These cases are why there are exposed bezel screws--removing the bezel provides access to the movement:
Even an ETA 2824 can be nicely decorated:
Here's a Zenith Captain showing its El Primero:
Finally, in the sculptured back department, here's an Ebel Aquatica with a 500m rating. That back is nicely done without just being laser-inscribed:
