Chronometer seconds hand replacement on Landeron 51

Hey guys! I recently finished service on Chronographe Suisse with Landeron 51 movement, and it went very well except one cosmetic issue. Alredy at purchase there was a problem with chronograph center seconds hand that is indeed very beautiful, but too heavy for this function. Every time resetting chronograph function it wouldn’t return to “0” but it slipped a bit when hammer hits heart ❤️ on seconds wheel. Didn’t bother me too much, since I inspected mechanic function and that looked O

Well if the picture shows result then well done! ? So far I worked on 1 Seiko and it was 6139B from Pogue and, that was so easy. I’m sure you guys know this well but it was first time for me to see center pinion with specially shaped pinion on dial end to fit hand. I mean that solves so much trouble. Wish to see this more often since I like to work on chronos the best, but this hand is like “sweet end” before casing. Well I guess practice, practice, practice...
