Update -- As long as you do not run the chrono, The Big Kahuna continues to run within 1 sec/day. Had I not seen it for myself, I would never in a million years believe that a fake, Chinese-made Daytona could achieve accuracy rates like that. Sheer madness................in a good way. More to come --

Update -- I had some time, found myself staring at gen Daytona parts & had idle hands. So I decided to move forward with some of the Kahuna's gen fixes. 1st up -- The Big Kahuna is now fitted with a gen "APH" dial and white gold handset. While I was messing around inside the case, I also replaced the 3 cheap & slightly chewed rotor screws with a fresh set of nicely finished/beveled gens. In my rush to see the new dial in place, I forgot to shoot photos of the inside. But I will get some good movement shots after the balance & auto-wind module work has been completed. Unfortunately, because the Kahuna's OEM hands were so accurate, the gens do not really show themselves off unless you view both handsets side-by-side. Then, if you know what to look for & you view them in just the right light, you can see the slightly warmer hue of the gen (white gold) hands versus the slightly cooler hue of the Kahuna's OEM (stainless steel) hands. As for the dial, not only are all of the fonts now correct -- obviously, being a gen dial they should be -- but the lume has the correct grainy texture rather than the smooth, paint-like white lume of the Kahuna's original dial. As previously mentioned, the Kahuna's dial is so good that some of these differences can only be seen via a loupe. But the gen dial's improved the overall feel of the watch a few percent. Some of the more astute viewers may have also noted the Christmas cheer on the dial in the form of a 116509 red chrono seconds hand. I have seen 2 other known gen 116520s fitted with these red chrono hands, but I do not know whether they came that way from Switzerland or if their owners had their watchmakers perform the same transplant I just did? Either way, I love the way a red chrono hand looks on a Newman & thought it would work similarly well on the Kahuna. Next up -- Swap reverser wheels for gens & the Kahuna's regulated balance for a gen free-sprung balance. Once all of the inside work has been completed & I have tidied-up a few details, I may top the project off with a display caseback to show off the beautiful 4130 caliber. Comments?
