Re: How many of you own a TUNA ?
"Badern"
Movt mods and swap for tunas are normally between the vintage 7549 300m tuna and 6309 divers. The 7549 quartz and 6309 movts are direct swaps ie ucan take the dial and movt of the 6309 and put in a 7549 300m tuna case and vice versa.
I have yet to come across a mod using the current 300m tuna case that uses 7C46 quartz.
I have also asked a watch modder if its possible to fit in any other movt into a 6159 tuna case - not possible.
Appreciate the insights! :)
In addition, is there any 3-click spring ring that can fit the 015 under the bezel?
I popped the bezel and noticed 2 flimsy spring clicks, while the puck on the other hand has 3 clicks, and they are mounted in a similar way...
Just curious as personally I like tighter action :)
