dsn 6154- first attempt


mellons

Recommended Posts

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

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...

I just picked up the same case, different dial, from dsn....nothing but good stuff to say....I had a similar one from river and think dsn's has a better quality feel to it...I've always thought that dsn,,,may not be the more accurate...but the quality is worth it. I've left it as is...but just begg'n for some vintage mods..

another step along the route: getting closer...
 
kemmner tuned engine with southy gaposis + athaya high collar double-pencil hands
back on with stock plexi
cp mod along with plexi to be dropped...it's sort of a 6154 on steriods!

quick and dirty gen comparison
 
case scaled-up to approx length and midcase height
 
photo of reshaped dsn case needs to be re-taken to get straight (looks shorter but that is photo)
 
lugs look ok if hole was re-located: underside of lugs looks good also. Case would be really super if reduced by around 1mm in height- say 0.8mm off underside and 0.2mm off topside (or 1mm total)

Edit: case has been reduced by approx. 086mm overall: 0.48mm off the top and 0.38 off the bottom
 
top reduction required bezel seat height to be taken down
 
bottom reduction was done without altering caseback or having to re-thread case etc
 
slight groove still there for gasket

just back from the works- i wanted to see how far this case would go (i.e. test to destruction): case is still around!!!

 

 

microwelding of lug holes and additional material added around crown (crown tapped) - thanks elias
 
new lug-holes drilles furrther along lugs and micro-welds cleaned up - thanks necky
 
i await athaya crown to see how it looks/ how much i need to take back
 
here are some shots of case as-is atm:

finally got build back together today

big thanks to elias who tapped case for athaya tube and got micro-welding done, and also to necky for tidying up welds and re-drilling new lug holes

work completed: existing lug holes micro-welded, new holes drilled and micro-welding additional material around crown tube. Case tapped and has athaya brevet crown and tube installed. I had tried a modded two-piece bezel along with a nightwatch slid thinner caseback- decided on keeping the stock (higher) one-piece bezel and thicker caseback and go for lower dome. Further modding required (more work to crown area + plexi to be lowered slightly). Build has southy gaposis + seagul 6497 from roland kemmner. More work to be done: shorten lug bars, lower plexi and more work to crown area.

revised dimensions as follows: lug-to-lug 54.64mm (wider), 12mm from bottom of dsn caseback to top of bezel, 15.5mm overall height.
