Movado M90 ref. 19033 Pulsations: originality check

Hello all! I'm looking for a vintage pulsations dial chrono. In addition to a Medico Compax, I am also considering this piece and was wondering if I could get some expert opinions on it.

It's a Ref 9033 M90 pulsations chronograph and would appreciate opinions on originality. Seller represents the dial, including the blue pulsations scale, as completely original and unrestored; hands and crown as correct and likely original. Case serial is 702781.

Many thanks in advance!

$16k which seems a bit high based on my research, but these pulsations dials are so niche it’s hard to find comparisons.
