Default Photo tutorial: How to remove mini tuna shroud

Thought I'd share how I was able to remove the plastic shroud from my 7C43-6020, keeping it in one piece (phew!). I read this thread first, which suggested putting the shroud and case in very hot water, but mine seemed quite flexible still so I didn't bother.

Disclaimer: The following steps might work for you, or the shroud might be too brittle and could break. Try at your own risk!

1. Remove both spring bars and the three cross-headed screws in the shroud, noting that the one next to the crown is a bit different - it has a shoulder. You don't need to remove the crown or bezel.

2. The shroud is now held on by being clipped over the edge of the case at the 6 o'clock and 12 o'clock positions. Using a flat tool such as a screwdriver, very gently prise up the plastic part between the lugs so the shroud slips over the case. Your mission is to not break the shroud and not scratch the case.







3. When that's done, don't try to force the shroud off completely. Carefully lift up the shroud on the crown side only. Leave the side with two screws as it is - we'll see why later. Move round the crown side and then unclip the plastic from between the other pair of lugs in the same way as before.





4. With both ends unclipped and the crown side free of the case, you should be able to lift off the rest of the crown, moving it up and away from the case slowly. In the picture below you can see the metal screw threads which extend into the case, so the above method is important to leave these intact.



5. That's it! Time to breathe again, wipe the sweat from your forehead, and give that watch the cleaning it deserves :-)

Yay, I cleaned it and got it back together without damaging the shroud!

It was pretty much the reverse of the removal process above, but one thing to be careful of. It's hard to re-clip the shroud over the case at 12 and 6 o'clock from the back, so I recommend putting the screwdriver under the shroud from the front, i.e. the bezel side. Lift gently and push, and it should slip over the case nicely.
