that movement is a Hangzhou 2189 movement, which has that distinct 'finger' over the stem. It's a rock solid movement, hand winding, non-hacking, 21600 bph, skeletonized, so somewhat like having a power reserve because you can see the mainspring. In this price range, you can actually find tons of skeletons using this same exact movement, as hangzhou tends to produce this movement expressly in its skeleton form.
