A NEW KID ON THE BLOCK
I just received my Yuki 6241 bezel/insert & I have to say that it corrects all but 2 of the obvious errors on aftermarket 62xx Daytona bezels. But before I get into the specifics, here are a couple of comparison shots of the Yuki (all left/top) vs the DW (all right/bottom)
One Hundred Ten
The most glaring problem with most aftermarket bezels is the too-widely-spaced 1-1-0, which the Yuki gets right. Unfortunately, the fonts are printed a bit too boldly (this, for me, is not a major issue since this is difficult to see without a loupe) & the overall printing quality is not up to the standards of the DW insert
UNITS PER HOUR
While many aftermarket bezels place the words 'UNITSPER' too close together, both the Yuki & DW get that correct. However, none of the aftermarket bezels (including Yuki's) get the spacing of each individual letter (or even the fonts themselves) correct, which is the 1st of its remaining (obvious) sins
Not All is Hunky-Dory
The other problem with the Yuki is that, like most aftermarkets, it lacks the flat-top '4' that Rolex used on inserts from the 50s (think 6542) through the 80s. Here is a gen for comparison (note the flat-top '4', flattened 'S' & wider spacing between letters)
Yuki's plastic insert is also flush with the top of the bezel, which corrects another sin of the DW & most other aftermarket bezels
Here are a few wristies with the Yuki bezel, which is also correctly sized to fit snugly around a gen T21 crystal without having to either pick up a Dremel or worry that it will fall off
THE BOTTOM LINE
Overall, because the Yuki finally gets the 110 spacing correct without introducing any other glaring problems, I think it is worth upgrading.
ADDENDUM
Not sure how I missed it, but the 7s are missing their top serif, which is almost as big a tell as the 1-1-0 was on the DW. So, yet again, 1 step forward & 1 step backward. This leaves my overall impression of the Yuki a bit less positive & turns a good bet into more of a luke warm recommendation. The scale remains tipped, slightly, in favor of the Yuki, but, now, only by a couple of hairs.
