I ordered one of dsn's new 6152 no cg builds recently to see what the case was like. Although the shape is a bit controversial some photos were very interesting. I suspected the case could make an alternative to athaya/river/silix 6154 set.
The stock model received is a very nice piece: solid construction, good qualith high-plexi, nice movement and 100% accuracy out of the box. This one had a rolerai dial, push-fit plexi and engraved stick-on plates inside. It really is the small details on dsn's watches that elevate them: the little rubber washer in the cg lever or in this case the dimple on the movement ring that slides into the groove inside the midcase stopping any ring movement internally.
Here are a few stock case set images (unmodded on timeband):
Notice the excess of material in the lug-ends (at the sides towards the bottom) and the accentuated length of the lugs. These two aspects of this case, the ones that made it an odd shaped case for a 6152, are the ones that both the silix and athaya case fall down in. The one critiscism of the athaya case seemed to be the shorter lugs, and the silix has a lack of material at the lug ends (underside). Both are superb cases in their own right.
Obviously athaya case (and river form photos) is the correct thin height so it has a huge advantage on all others due to cost of machining and also labour involved in getting creases. Anyway I wanted to give this a go and see how the stock case would look without any machining and no huge reworking of lugs. The only slight mod atm of the lugs is to counter-sink the hole for the (very nice) vintage spring-bars to make the holes visually bigger (thanks southy for idea!)
here are a few in-progress shots
nice movement
here is a temp mock-up of reshape (almost done) with modded necky plexi. Case has been reshaped with crease all round, crown lightly modded also. Final dial/ hand configuration to be decided and i will probably revert back to a lowered high-plexi (probably gaposis + athaya high hands)
My own conclusion is this this case set could be the basis for a seriously good finished case- if someone like nightwatch was to get his hands on this and work his magic, machining top and bottom and also re-threading midcase for caseback- you could end up with a thin case, good long lugs and also plenty of curvature under the crease at the sides. For ocd members you could micro-weld lug holed and re-position also...
