Crown modding, 420 case 2416B mvt

[PlanetSimon]

Hi all,

Looking for some advice here. Just replaced a stem & crown on the above (new one has Vostok 'B' insignia on the crown) and something has gone wrong.

New stem went in fine but now doesn't lock. On unscrewing, it will come out to hand-winding position but then does not continue to hand setting position. instead, the stem just comes out completely.

Could it be the stem lock has become permanently depressed? If so, how to rectify please?

Thanks.

ps crown & stem obtained from Meranom, specified as 420 with B mvt compatible so I'm confident the stem is the correct one.

Had a similar problem with these vostok crowns. It took me a while to get it in correctly because the crown is so wobbly when it's not screwed down. Just try to turn the stem until it fits. Good luck.

Ha!

Just sorted it. Took 2 easy steps.

1) Walk away from the job for a bit. Do something else unrelated.

2) Open the case back, screw crown in completely, take a pair of angled tweezers & physically push the stem towards the centre until it clicks. Did the trick.
