Authentication

The icehardened case is the story; any deep scratch on a DA36 is a major anomaly worth investigating.

Known issues in the market
  • Deep scratches on the case are nearly impossible under normal use; any deep scratch points to impact with a very hard object or a non-genuine case.
  • The icehardened steel cannot be polished with standard jewelry tools; any DA36 showing heavy polish has been incorrectly serviced.
AreaWhat to checkWhat is correctRed flag
caseCase surface conditionNear-scratch-free surface consistent with icehardened steel; light contact marks onlyDeep scratches on the case; indicates non-genuine case or severe impact
casePolish indicatorsOriginal brushed/satin surface texture intact; no signs of buffing or polishingPolished case surfaces; icehardened steel cannot be polished conventionally
movementETA 2824-2 movementETA 2824-2 visible through caseback; appropriate Swiss auto movement for this referenceWrong movement; movement swap
Common legitimate replacements
  • Crystal; sapphire standard.
  • Crown; verify Damasko-signed crown.

Authentication guide

Last reviewed June 2026

The DA36 is Damasko's entry automatic, built on the ETA 2824-2 in an ICE-HARDENED case. The caseback engraving "ICE-HARDENING" is the practical provenance marker for the hardened steel. The anti-magnetic properties and case hardness are measurable but require lab tools; the caseback is the accessible check.

Known reproduction risks

toggle
MEDIUM

A standard ETA 2824 watch in a similar-looking case presented as Damasko.

  • "ICE-HARDENING" caseback engraving is the key check; a generic caseback is wrong
  • Case finish should be exclusively matte-brushed; any polished surfaces suggest a non-Damasko case

Dial variants by era

toggle
EraDescriptionIdentifiers
2010 to presentSport automatic; black dial; matte brushed ICE-HARDENED case; no date or date at 3.
  • "DAMASKO" on dial; "DA36" designation
  • Matte brushed case finish (ICE-HARDENED steel does not accept high polish)
  • Crown tube made from non-magnetic alloy (slightly different finish from case)
  • "GERMAN WATCH" or "MADE IN GERMANY" on dial
  • "SWISS MOVEMENT" notation (ETA base)

Service part flags

toggle
Case Finish

Original: ICE-HARDENED cases are exclusively matte-brushed; they cannot be polished to a mirror finish without removing the hardened layer.

Replacement tells
  • A polished or mirror-finished Damasko case indicates the hardened surface has been removed; the case is no longer ICE-HARDENED
  • Any swirled or circular polishing marks on the case are a sign of post-factory surface modification
Crown Tube

Original: Non-magnetic alloy crown tube; slightly different surface sheen than the case.

Replacement tells
  • A crown tube with identical finish to the case may be a standard steel replacement rather than the specified non-magnetic alloy

Case back markings

toggle
2010 to present
  • "DAMASKO" on caseback
  • "ICE-HARDENING" engraved on caseback
  • "DA36" model designation
  • "MADE IN GERMANY"
  • "SWISS MOVEMENT" or ETA caliber reference
  • Serial number

Movement tells

toggle
  • ETA 2824-2 is a straightforward caliber to service; any qualified watchmaker can work on it.
  • Rotor may be Damasko-signed or ETA with Damasko finishing; confirm with seller.
  • After service, confirm the ICE-HARDENING caseback engraving is present; a replacement caseback without the engraving removes a provenance marker.
