Keeping the three Lebois & Co Heritage Small Seconds variants straight

The safe facts to carry forward are the ones Fratello actually reports:

• The line named in the source is Heritage Small Seconds.
• The three interpretations are called Numeral, Baton and Script.
• Fratello describes the three as sharing the same case.
• Fratello reports a COSC-certified movement.
• The historical framing is broad: each version is said to draw from a different moment in Lebois & Co’s past.

The wording matters. “Same case” is not the same as a confirmed case reference, case number or set of dimensions. “COSC-certified movement” is not the same as a named calibre unless the calibre is provided. A reference number, serial number, case number and calibre belong in separate record fields.

For a collector record, the variant name is a real identifier even before a reference number is known. Recording only “Heritage Small Seconds” could make a later invoice, warranty card or service document harder to match against the watch.

A clean entry would keep the model family and the variant apart:

If a later maker page, warranty card or invoice gives a reference number, record it exactly as printed. If a serial number appears on private paperwork or photographs, mask it before sharing. A warranty card date, if present, records a sale date; it should not be treated as a production date.

COSC is the Contrôle Officiel Suisse des Chronomètres, the Swiss institute that tests watch movements for precision and certifies movements that pass as chronometers. Because the supplied report says “COSC-certified movement,” the careful record entry is just that: the source reports a COSC-certified movement.

Avoid expanding the note into claims the material does not establish. The report excerpt does not give a rate result, a certificate number, a timing printout or a named calibre. It also does not say anything about how an individual owner’s watch performs now.

For a personal record, the strongest wording is source-based: “Fratello reported on October 20, 2026, that the Numeral, Baton and Script Heritage Small Seconds interpretations share a COSC-certified movement.” If a physical COSC certificate or maker documentation later appears, file that separately and note exactly what it states.

The Fratello item is product news, not a condition report. It does not establish that any particular watch is authentic, original, serviced, running within specification or presently water-resistant.

If a collector is evaluating an actual example, case-specific questions should go to a qualified watchmaker or the maker’s service channel. Photographs and paperwork can help organize the question, but they do not replace an inspection. Keep condition observations separate from documents: an owner’s note, a dealer description, a service invoice and a watchmaker’s report are different kinds of evidence.
