A guide for this piece: about $3,030, 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.

The Piece
The historical identity is SBGS006 with case/movement designation 9587-8010, quartz operation and a date display. The recorded K18 yellow-gold material and 138.2 g whole weight do not substitute for an assay or establish a pure-gold content. Exterior refinishing, a movement inspection and battery replacement are recorded without dates. The bracelet was still described as slightly stretched and marked. A refinished appearance therefore should not become an unused-bracelet claim, nor should the older quartz designation be silently replaced by a modern 9F specification.

Condition
Historical grade A includes slight bracelet stretch, fine lines and point marks, dullness on the hands, rubbing at the dial edge, and point marks or dullness on lugs and end fittings. Fine lines and point marks also occur underneath the lugs and on the back. Refinishing does not erase these specific condition disclosures. See every photograph before deciding; they are part of the description. See Japanese condition ranks.
Authenticity & Care
Keep the watch dry until its present seals and operating condition have been examined. Confirm the correct setting and winding sequence for the actual movement with a qualified watchmaker. A historical inspection or repair does not establish current rate, reserve, battery life or water resistance. No transferable maker or third-party service coverage is promised. Check bracelet fit, clasp engagement and link wear separately from the case finish. A prior battery change is not evidence of remaining charge, and no current annual accuracy figure is established.
Delivery from Japan
Ask about protective packing, availability and destination requirements before dispatch; no unverified transport or maker-service promise is made.
