Three watches we currently have on hand, and what actually matters when you are evaluating one — this specific reference, not the brand brochure version.
Tudor Black Bay Ceramic (M79210CNU-0001)
The Ceramic is the Black Bay that went technical: a full matte-black ceramic case around a METAS-certified Master Chronometer movement — the same certification standard Omega uses, which at this price point is quietly a big deal.
What to check on a pre-owned example:
- The case. Ceramic does not scratch the way steel does; it chips. Inspect lug edges and the bezel rim under raking light. A clean ceramic case is genuinely clean — there is no polishing away a chip.
- The certification card. METAS pieces shipped with their chronometer documentation; a full set should include it.
- The rate. Master Chronometer means tight numbers — ask any seller how the example is running, and expect a straight answer.
Omega Speedmaster 38 Co-Axial (the "Ice Blue")
The 38mm Speedmaster is the one Speedmaster line where the dial does the talking — and the ice-blue dial is the one people ask for. It wears smaller and dressier than the Moonwatch, with a self-winding co-axial movement rather than the hand-wound caliber, which makes it the everyday Speedmaster.
What to check:
- Dial and subdial edges. The oval subdials are this reference's signature; look for even printing and clean edges under magnification.
- Bracelet stretch and clasp wear. It is a daily-wear watch and often lived like one.
- Service position. Co-axial movements run long service intervals, but ask when it was last done — or buy from someone who timed it and will tell you.
Cartier Ballon Bleu (W69012Z4)
The Ballon Bleu is bought with the eyes: the floating crown guard, the curved case, the roman dial. Mechanically it is straightforward — which means condition and authenticity carry almost all of the value.
What to check:
- The crown and its sapphire cabochon. The signature detail, and the first thing a refinished or messed-with example gets wrong.
- Case symmetry. The curved case shows sloppy polishing instantly — look along the case flanks for waviness.
- Papers matter more here. Cartier fakes are common at this price point. Buy an example someone has actually opened, or from someone who did.
The shortcut
All three of the above are in the studio now, professionally authenticated and photographed — the photos on each listing are the exact watch. See them in the collection, and if one is already gone, Robert can source the reference — that's the job.
