Looking for opinions on this...
I've got an original 7C43-7000. Hands and dial are nice, movement works well, case and crystal are a bit worn.
I'm considering having the case machined and drilled for a shroud {regular tst}.
Here's my reasoning on this one: the 7C43 movement is a proper tuna movement; anti-magnetic with 7 jewels instead of only 5 like in the 7548. It's dial says "professional", it has a unidirectional bezel and a proper "screw down" crystal...in essence, a proper tuna minus the shroud. To make this professional diver complete, it really should be kitted up in tst fashion.

So, here's my question...should this one be left as is? Or should it be made into a proper professional tuna diver {like perhaps it should have been from the beginning}?

Is it more valuable as a standard 7C43 or a modded tst 7C43?

Another important factor for consideration is that I have a second 7C43 in very nice condition so it wouldn't be as if I would be left without an original reference piece for my collection.

All comments welcome!
Mike

Pics Mike?

I don't see why not if you want to do the work.
They fetch strange prices depending on condition but anything from 150 to 275+ I've seen them go for.
Mostly around the middle. FJ they come up sometimes and I can see them becoming more desirable over time as they're lovely watches.

I'm not sure but I believe the case is transferable to a few other slim cases so you could always test this out and if it goes wrong you could source a spare case over time?

These are not very common (especially the "professional" dial) and I would vote for let it be.
you can easily make a "tuna" out of a 7548...

Ok.
That's one vote for tst mod {proper tuna} and one vote for leave as is.
Just to bring everyone up to speed here, I have quite a few standard 7548 divers but only two 7C43 divers.
One of the 7C43 divers is in pretty worn condition {crystal and case appearance}.
I've been thinking more about the overall utility of these 7C43 divers and it occurs to me that of all divers, these are the most likely candidate for a proper tuna kit {tst conversion}.
The dial and hands are in remarkable condition and the movement works perfectly.
Please take a moment to weigh in on this.
{thanks to Guy and Nimiseik for their previous comments}.

I'm swaying more to the leave it, Mike. However if it's something you've been considering for a while then why not go for it.

What's the case like? Is it as good looking as the dial and hands look to be?

If it was me and I wanted to do this mod and had given it a lot of thought then it would depend on how beaten the sacrificial watch was in order for me to get motivated to see it take on a different life.

If it was swap the slightly worn hands or bezel or dial etc generally speaking for aftermarket parts because they look newer and freshens the watch up then it's a no from me. But with a mod and something you've wanted to do for a while. Then one less 7c43 in the world might not hurt?!

Or would it? Mahaahahah... Evil laugh. Up to you Mike and good luck. Will you regret it more than being happy with the outcome!?

Ok.
It seems like the forum has spoken.
The 7c43 is currently in route to the UK. I'll place a "hold" on the work temporarily and instead opt for a case refinishing. This one has been slid around a bit. Nothing too deep that can't be lightly massaged.
I will instead send off another case {7548}, that is somewhat more abused. That one just came in and I honestly didn't know what to do with it so perhaps it will do well in tst form.
The 7c43 will be restored to it's original glory...shiny on the bright parts and brushed on the other parts.
And thusly, another 7c43 has been saved for all to admire and enjoy...or rather; for me to admire and enjoy.
Thanks to all who weighed in on this one. I'll post some photos after the restoration is complete.

Maybe the movements could swap, but the cases are different due to the screw-down crystal retaining ring. The decision has been made though, to restore the 7c43 to as new condition.
I guess that's the more responsible thing to do here. Seems like everybody who weighed in on this said the same thing.

Good decision my friend!
Happy to help saving a 7c43's life (even if only for a while :))

Thanks for steering me in the right direction on this one. Still think my logic was sound on it since this has the upgraded 7 jewel movement and screw down crystal retaining ring so it really should have been a tuna, but I can modify any other watch and I have a few tunas already.
You were right to advise me the way you did though.
If I would have had machine work done on that case, it could never be returned to original condition.
This one can now be restored and I'll post photos when I get it all done.
Thanks again!
Mike
