Fitting the Plexi: This plexi is a little tight on one side. This is easy to correct.

After polishing the Plexi is super clear and like glass.

The Plexi is a nice firm fit. To seal the Plexi and make water-tight use clear silicone. Do NOT Seal the Plexi just yet. The Plexi will need to be removed if you plan to solder the Stem Tube to make the case water tight (optional).

Its not necessary to make water tight but if you do then follow these tips.
There are three areas to seal A) The Case Back B) The Stem Tube and Crown C) The Plexi.


First we need to solder the Stem Tube to the case, this is how the authentic Vintage Panerai 6152 cases were sealed.

ALWAYS set-up the Stem Tube Crown and cut the Winding Stem to the correct length BEFORE soldering. The Stem Tube can sometimes provide fine adjustment by screwing in or screwing out a little. Note there may be a gap at the bottom of the stem tube, this is ok, below I will show you how this is filled with solder.

Run a little solder around the stem tube. There will be a “gap” at the bottom of the Stem Tube between the Stem Tube and Case. Solder from the top first, eventually the solder will run to the bottom. Let it harden then fill with solder. Do NOT try to fully screw the Stem Tube into the case so there is no gap, if you do you may find that the Stem Tube is too short.
