The quintessential PuristS' stealth watch must be the St Gallen PuristSPro All-Black RESCUE.
See how the real carbon fibre dial changes stealthily with the changes in light?
Also the shaded black SuperLuminova for the PuristSPro logo at 6 o'clock that is only revealed by harsh light of the flash-gun.
In real use, the logo is not seen black-on-black dial until it glows.
The only time that the PPro ABR watch is NOT stealthy is when we have an ABR GTG
Then, we pretty much draw attention with our wristscans.......
