A guide for this piece: about $471, 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.

A Sinn automatic chronograph in a gold-coloured case, with a champagne dial, Roman numerals, a moon phase window and a calendar scale, on a brown stitched leather strap.
The Piece
Three subsidiary registers occupy twelve, nine and six, with the moon display at three. A red crescent-ended pointer reads the numbered scale around the dial.
The case has a smooth bezel, a crown between two chronograph pushers and a steel case back. The champagne dial is signed Sinn, with Roman numerals, a calendar scale around the edge read by a red crescent pointer, a moon phase window at three and three subsidiary registers.
The watch was as running and the original numeric 4–5 category describes its appearance, with some marks. The strap is a brown stitched leather strap and it is not original.
