Now I had the time to compare the BBR (ice blue) with my old APS CHS (black). To anticipate: The BBR is better in terms of movement and functionality. I'll leave the visual aspects and details to you to judge.
The external dimensions are almost identical. Both are exactly 11.4 mm thick.
Functions: The APS offers hour/minute/day/day of the week/moon phase. The month can be set via the pusher. The week runs as large hours (GMT), but cannot be set separately. The leap year can also be set, but is also adjusted when the month is set. Adjustment via the pusher is generally a little awkward.
The BBR offers hour/minute/day/day of the week/moon phase. The month and leap year can be set via the pushers. The week can be set via Pos 2 of the crown, but does not run with it, so it has to be adjusted every week.
Dial/hand/case: Both are well made. It is noticeable that the bezel on the BBR is thicker and therefore the dial as a whole is slightly smaller than on the APS. This makes the BBR look somewhat stockier. The details (moon disk, hands, Grand Tappiserie) are good on both, but not perfect.
Bracelet: It is noticeable that the phases on the BBR are smaller and more finely finished. From a purely subjective point of view, the strap on the BBR is slightly more finely polished, while the strap on the APS is somewhat sharper. On the other hand, the surface of the APS is more finely polished.
When I compare the two, I come to the conclusion that the BBR is the better watch simply because of its better functions. Subjectively, however, the APS looks slightly better (probably because of the narrower bezel)
But that doesn't matter for the purchase decision, as the CHS APS was only produced in a very small batch anyway and is no longer available
P.s.: This model (Yoshida Platinum, 2nd batch) with the silver subidals is not repped by BBR. The grey/black BBR model is the first Yoshida batch with the black subdials.
p.p.s.: Sorry for the rather bad pictures. I lent my tripod and my big photo light to my son. And shooting macros from the hand with only a small lightbox is not a rewarding job ;-)
