Heavy corrosion, deep pitting, stripped threads, bent or missing parts.
🎯 Watch Dials	Perfect finish, no flaws, luminous intact, printing razor-sharp, NOS.	Very light patina, all markers present, original, visually appealing.	Uniform patina, minor edge wear, faint marks, printing fully legible.	Visible scratches, flaking near edges, possible touched-up markers.	Severe damage: missing indices, large paint loss, illegible printing.

Plating wear on edges, logo slightly faded, threads engage well.	Worn knurling, aftermarket, some corrosion, threads stiff.	Severe corrosion, broken stem interface, non-functional, salvage only.
💎 Watch Crystals	Flawless, no scratches or chips, OEM crystal, perfect clarity.	Micro-scratches only visible under loupe, no chips or cracks.
