Yes, the BP01 have the hour counter hand glued on the dial at 3 o'clock.
The datewheel for eta7753 in gen a23322 is exclusive to breitling and very hard to find on the market.
The datewheel on the modified a7550 of BP01, although has correct font, does not share the same dimension with the datewheel on eta7753. FYI, it's even different from the eta7750, i know because i have like 5x 775x of different variations.
So basically, the correct datewheel is very hard to come by and I have to live with the stock datewheel for now.
