Authentication

The Streamliner Centre Seconds pairs the HMC 200 movement and fume dial of the Endeavour family with a cushion-shaped case and a fully integrated in-house bracelet. The bracelet-to-case junction and the cushion case shape are the two primary identifiers versus the Endeavour line.

Known issues in the market
  • The integrated bracelet is the key differentiator; a Streamliner case paired with an aftermarket or wrong bracelet is a common pre-owned issue.
  • The cushion case shape is distinctive and not round; a round case being presented as Streamliner is a clear mismatch.
  • Fume dial condition is the same concern as the Endeavour: fragile surface, no refinishing possible, any damage is permanent.
AreaWhat to checkWhat is correctRed flag
braceletIntegrated bracelet fit and finishingBracelet flows seamlessly from the lugs with no gap or step; alternating brushed and polished link surfaces; the clasp bears the Moser logo; links are solid, not hollowGap or misalignment at the lug-bracelet junction; uniform finish across all links; hollow or light links; clasp without Moser markings
dialFume dial with no textGradient fume with no brand or model text; applied hour markers; date at 6 if present on the variant; color consistent with documented Streamliner palette (blue, grey, green)Any text on the dial; gradient inconsistency; incorrect color for the claimed variant
caseCushion case shape and water resistanceDistinctively cushion-shaped case (not round); 40mm; 120m water resistance; screw-down crown; case height 10.5mmRound case being presented as Streamliner; push-pull crown instead of screw-down; water resistance inconsistent with specs
movementHMC 200 peripheral rotorIn-house HMC 200 with peripheral winding; 72h power reserve; Moser signed and numberedCentral rotor instead of peripheral; non-Moser movement base; unsigned
Common legitimate replacements
  • Bracelet link removal for sizing is routine; confirm correct link specification for the documented bracelet.
  • Crown replacement at service is standard; correct screw-down crown is required.
Expert resources: H. Moser & Cie customer service for serial verification. Streamliner bracelet details are documented in press materials and collector forum photos.

Authentication guide

Last reviewed June 2026

The Streamliner is Moser's integrated-bracelet sport watch. The fumé dial carries over from the Endeavour but with a date window and a bracelet machined from the same steel billet as the case. Cal. HMC 200 is shared with the Endeavour family.

Known reproduction risks

toggle
HIGH RISK

Non-Moser movement with bolted-on bracelet rather than integrated machining

  • Visible seam or gap at the lug-to-bracelet interface
  • Bracelet that removes with spring bars rather than requiring the machined integration mechanism
  • ETA or generic movement through the exhibition caseback

Dial variants by era

toggle
EraDescriptionIdentifiers
2020 to presentFumé dial in blue, grey, or green. The Streamliner Concept version omits indices and brand text; standard production versions include applied H-shaped indices. Date window at 3.
  • Fumé gradient from opaque center to lighter periphery, identical philosophy to the Endeavour
  • Applied H-shaped or lance-shaped indices on standard production (absent on Concept version)
  • Date window at 3 with no cyclops, flush with the flat sapphire crystal
  • Brand name typically absent from the dial face -- on caseback instead
  • Sword-style or baton blued steel hands matching the Endeavour family

Service part flags

toggle
Integrated bracelet

Original: The bracelet is machined from the same 316L stainless steel as the case. Integration is seamless with no visible joint at the lug/bracelet transition. Flat-link design with horizontal brushing and polished bevels on outer link faces. Butterfly deployment clasp engraved with "MOSER".

Replacement tells
  • Any visible seam or step at the case-to-bracelet transition -- genuine integration is completely flush
  • Bracelet links with inconsistent brushing direction -- horizontal faces should be brushed, vertical bevels polished
  • Aftermarket deployment clasp without the Moser logo or without the butterfly action
  • Bracelet that attaches via spring bars rather than the machined integration design
Movement (Cal. HMC 200)

Original: Identical to the Endeavour version. All HMC 200 characteristics and finishing apply. Exhibition caseback shows the same architecture.

Replacement tells
  • All Cal. HMC 200 service tells from the Endeavour guide apply here without modification

Case back markings

toggle
2020 to present
  • "H. MOSER & CIE." and "STREAMLINER" on caseback
  • "CAL. HMC 200" movement designation
  • "6201-1200" reference number (or variant)
  • 120M water resistance
  • Exhibition caseback showing movement

Movement tells

toggle
  • Cal. HMC 200 service tells are identical to the Endeavour Centre Seconds. The 72-hour power reserve, 28,800 bph beat rate, and double Straumann hairspring are the same caliber.
  • The Streamliner specifies 120m water resistance. Any signs of previous water intrusion (cloudiness inside the sapphire crystal, corrosion on movement bridges) should be investigated before purchase.
