The bracelet of the MKF V6 when worn by a wearer with a smaller wrist size (6.5 inch or smaller) will have a gap. This is because the bracelet does not wrap around close enough on smaller wrist, in your case you should not have any problems. There are numerous threads with pictures that explains this, you'll just have to search for them. There are also some DIY solutions to fix the problem.
The blue dial of the MKF is considered to be the best amongst reps whereas the blue dial (white also) of the PF is plagued with misaligned markers which are attached to the dial using only double stick tape, the markers of the MKF are attached properly on the dial and are straight. You just have to be careful when reviewing your QC pictures.
The stock DWO of the MKF V6 is better than the stock PF DWO. A replacement DWO is offered for the PF, but that would require modification. At this time there is no replacement DWO for the MKF V6, however it is being looked into.
The movement engravings on the PF model are better than that of the MKF V6 model, mainly because the words, "adjustment" and "cold", are misspelled. These flaws on the movement can't be seen while wearing the watch, so if you can overlook this, you'll be okay.
On the MKF V6 blue dial, the greenish lume is also present on the gen blue dial, so no problem there as far as I can see.
I suggest you do some further research on these two reps, it'll be enjoyable. Myself, I'm still waiting for the elusive V6F model, been over two years now.
Glaude , can you add anything that I'm sure I missed? Thanks and I'm glad you're on the RWI staff. Belated welcome.
