This observation has not got vigorously scientific data behind it, so feel free to take issue with everything . . . .
For many watches I see photos of on the affordables forum, the alignment of the date wheel within the date window is often highly inaccurate. At the London G2g I noticed that the watches with 2824s seemed to be significantly better. I believe I noticed that the 9015s were amongst the imprecise watches, but, you know, beer and high-velocity chatter. . . . .
I was wondering what technically was behind the superiority that the 2824s enjoyed, what gives them greater control over their date wheels?
