Smiths Set Lever- Is it Genuine?

Finally getting around to this lovely Smiths W10. While the crystal suffered trauma and much sloppiness in previous openings of the case back it is in otherwise excellent shape and a joy to work on…

The previous work on the movement shows only in a few screw slots…with perhaps one exception: I’m told these movements often suffer an obligatory broken set lever due to poor design and tempering combined with the need to depress the set screw to disengage the stem.

Perhaps due to great demand I had no trouble finding a replacement- Cousins has 400 generics in in stock. I would however prefer to stay as original as possible which brings me to the question: I’ve noticed some of the levers of this shape have countersinks yet this one does not. Would that indicate this one is a generic replacement or perhaps did Smiths use this design for the militaries?  Any intel out there?

Why would the set lever be countersunk? The screw comes in from the other side. 

Sorry, mate- I was referring to the screw holes- see below...

The ones I have repaired many years ago were always countersunk. Nearly every one that came in the set lever would be brokeen so I had a good stock of parts for this movement. 

Thanks. I wasn't certain if there was a difference for the mil spec but generic it must be...

      Nice interesting diver Razz, i have a sheffield dress watch, different movement altogether. Could be a wrong motion works part, how does the setting feel before fitting the cannon pinion, clutch and intermediate wheel meshing ok ?  The less traditional setting design could be suspect, the second wheel has a slip clutch assembly, that most likely needs looking at. LA is 42 ° Razz Tbh i  much prefer to call the complete unit the lever, then use the seperate names for all of its components. Such as guard pin, fork, fork horns, fork slot, lever arm, pallets , pallet arms, pallet slot, pallet stones. I suppose pallet fork is the combination of the two opposite ends that make up the lever, its also called the anchor which is descriptive of its appearance.  Its a pretty basic 1930s  swiss lever movement H and yes Nev was meaning the pallet fork.

      The pallet fork should really be called a lever, English lever, Swiss lever etc but most people including myself call it a pallet fork.

      Seiko 6309a diver crown replacement

      By RichardHarris123 · Posted

      Seiko have case numbers, I  can't see it on your photos.  If you can find that we can look for a genuine crown.  If not, you need to measure the diameter of the stem, the distance between the lugs and the depth of the lugs.  The case number will be something like this.

      I'm not sure what kind of movement this is, but I'm curious to know if you're using the word "lever" as a synonym for "pallet fork"?

      Actually kind of rough, maybe munute wheel pinion problems? Is the 2.73mm canion oinion which seems rarer and not availble on Cousins UK. The seconds hand works and suprising nice amplitude but don't know the lift angle and BE this one says 17 j but is a pin pallet as well. Cap jewels on the escape and drive train pivots. Interestingly in has both water proof and shock resistant on the caseback and dial. Puts this around 1969 or '70? The double bezel that works independently is cool has the pi symbol on each. Wonder if it can be used like a slide rule ir something...
