Hi buddy ...
I just stumbled on your old 7016 thread and wonder if you ever found that handset.
If NOT you could check wholesaleoutlet on eBay or Tiger Concept website ... I'm pretty certain you can get a decent 7016 handset for ETA 2824-2 from them.
1 - Hours and minutes hands will be a direct fit as ETA 2824-2 and ETA 2451 (base caliber for Tudor 2483) share the same specs ... H : 1.50 / M : 0.90
2 - Fitting the seconds hand will be tricker but doable ...
2824-2 seconds hand tube is 0.25mm and 2451 seconds hand tube is 0.21mmm so you can suqeeze the tube of a 2824-2 seconds hand until it fits a 0.21mm pinion
Method 1 :
Source a 0.21mm smoothing broach (better than a cutting broach for that process)
Insert the broach in the tube and slightly (really slightly) press the tube with tweezers ... that should do the job.
Method 2 :
Use a quality fine pin vice ... Ensure all 4 tips on the pin vice close evenly and carefully place the tube of the second hand in it.
Do it up until the jaws of the pin vice are just touching the tube but putting no pressure on it. Then do it up 2 or 3 degrees tighter.
Take it out and check the fit of the hand, if still loose repeat.
Important :
Be very careful because if you go too far you may spit the tube, or at the very least will need to then broach out the tube, and then you will need a set of very fine cutting broaches
You are seeking just enough friction to fit the hand on the pinion fixed, as excess pressure is an invitation to damage the pinion, or jewel at the other end of pinion
I use method 1 as it's easy to leave the end section of the tube wide so to facilitate entery of the seconds pivot into the tube and just tighten the mid- section of the tube or farther close to the hand.
I never used method 2 but I read people did it with success.
