Partly verified: what this means

Last researched 3 November 2026 · 5 sources

German maker of pilot's and diver's watches.

Until Sinn Spezialuhren traces its gold and gemstones to the mine, it can't show that the miners who dig them are safe or fairly paid.

Why it's graded Lacks transparency

  • Not met: Meets 3 of 6 Good requirements.
  • Holds the grade back: It relies on high-risk mined materials it can't trace. That alone means a poor grade until it takes steps to trace them.
  • It isn't Harm on record, because there's no serious confirmed problem on its record.
  • Lacks transparency is still a poor grade: in supply chains like this, workers who can't be seen to be treated fairly are usually underpaid or unprotected.

How grades are decided

Good requirements 3 of 6

  • Not met: Pays a living wage, or holds a strong fair-pay certificationLiving wage: no evidence
  • Met: Respects worker rights
  • Not met: Supply chain independently audited or certified, or at least 80% made in countries with strong labour standards
  • Met: No child or forced labour findings or links
  • Met: Names the factories or farms that make its products, or is fully certified by a scheme that holds and audits that listMakes its products in its own factories
  • Not met: Conflict-free: diamonds, gems and gold traced to the mine, lab-grown, recycled or Fairmined (the Kimberley Process alone isn't enough)

Red flags 2

  • Red flag: No evidence it pays a living wage
  • Red flag: Relies on high-risk mined materials it can't trace
  • Red flag: Fails its category's raw-material check (means Lacks transparency)

Evidence

What we found

  • Risk across the industry, not a finding about this company: gold and gemstone mining are linked to child labour, forced labour and mercury poisoning.
  • Owns or runs its own production
  • Relies on gold and gemstones from artisanal mines where workers face mercury poisoning, silica dust and deadly collapses. It hasn't shown any steps to trace these materials to the mine, so it's graded Lacks transparency until it does.

Research notes Sinn assembles its watches at its own headquarters in Frankfurt-Sossenheim, with a service and assembly branch in Dresden opened in 2022. Its cases are made by Sächsische Uhrentechnologie Glashütte (SUG), a company co-founded by Sinn owner Lothar Schmidt, and its movements are bought from Swiss makers Sellita, La Joux-Perret and Concepto and modified in-house. It publishes no supplier code, supplier list, audit results or living wage commitment, and gives no origin for dials, bracelets and straps are made.
