Research Focus: Setting Sequence
The stated Automatic gives 279178-0002 a mechanical route into setting sequence. Record the relevant operating sequence or architecture before relying on caliber wording; functional evidence is valuable precisely because it is independent of exterior resemblance.
What to Verify: Bezel Registration
The listed bezel makes bezel registration a natural geometric reference on 279178-0002. Compare frontal registration with a neutral frontal frame; construction and stacking are generally more reliable than perceived color or reflection.
First-Link Articulation
On 279178-0002, first-link articulation should determine how much weight each observation receives. Repeatable structure and function generally outrank lighting-sensitive appearance, while provenance provides a separate supporting channel.
Evidence Question — Polishing History
Condition complicates polishing history on 279178-0002. Wear, polishing and service replacement can alter the same details used in authentication, so original manufacture should be separated from later intervention before origin is discussed.
What to Verify: Service-Part Possibility
Condition complicates service-part possibility on 279178-0002. Wear, polishing and service replacement can alter the same details used in authentication, so original manufacture should be separated from later intervention before origin is discussed.
Confidence Boundary
The conclusion for 279178-0002 should never be stronger than the evidence. Structural and functional observations deserve priority, while finish, color and provenance remain supporting context.


















Justin Yaung –
I wasn’t looking for the most complicated design, but I wanted some distinctive details. The 18kt Yellow Gold and Folding combination is a practical touch and fits the overall styling. The details are what make this version work for me.
