A guide for this piece: about $711, based on the 10% US charge on the declared value of goods made in Japan.
The final figure is set by US Customs and depends on where the piece was made and the kind of object it is. Many antiques over a century old carry no ordinary duty; most jewellery and leather goods add a single-digit rate.
With EMS, any charge is collected by your postal service on delivery. For pieces of significant value we can often arrange duties prepaid before dispatch.

Two overlapping circles organise this silver-dial Grande Seconde Quantième: hours and minutes above, a much larger seconds display below.
The Piece
A red-tipped hand points to the date around the lower register. This figure-eight arrangement belongs to the Grande Seconde design vocabulary, while the steel case and black strap keep the dial architecture prominent. The historical item account records a timing adjustment but gives no date or before-and-after test sheet. Case diameter, thickness and 93 g band-inclusive mass are historical measurements, not newly verified specifications or a packed transport weight. A non-maker box must not be presented as an original Jaquet Droz full set.

Condition
Historical A grade, with minute rubbing across case and buckle and some use to the strap. No especially conspicuous scratch was then reported. Timing adjustment is an earlier intervention, not evidence of a full overhaul, current accuracy or remaining power reserve. Strap lining and fastening need a present check before wear. See every photograph before deciding; they are part of the description. See Japanese condition ranks.
Authenticity & Care
Keep the watch dry pending a current seal and water-resistance assessment; historical inspection is not a new pressure test. Have a qualified watchmaker check winding, timekeeping, fastening and any loose or chipped glass before wear. Use only a soft, non-abrasive cloth on secure exterior surfaces, and do not open the case or polish gem settings at home. Historical documents require matching to the actual reference and serial; they do not establish current performance or transfer another business’s service terms.
Delivery from Japan
Ask about protective packing, availability and destination requirements before dispatch; no unverified transport or maker-service promise is made.
