Why buy Japanese watches from Japan

Japanese brands sell models domestically that never reach overseas markets, and the secondhand supply of both modern and vintage pieces is enormous. Prices are frequently lower than abroad, condition is often excellent, and the selection — across decades of Seiko and Citizen alone — is unmatched. For enthusiasts chasing a JDM-only Seiko, a vintage diver, or a Japan-exclusive G-Shock, the source market is Japan.

What to look for

• Seiko — from affordable Seiko 5 and vintage divers to Grand Seiko; deep vintage catalogue and many JDM references.
• Citizen — vintage automatics, Eco-Drive, and domestic models.
• Casio — G-Shock, including Japan-exclusive (JDM) editions and collaborations.
• Orient — well-regarded affordable automatics.
• Vintage divers & chronographs — strong collector demand; condition is everything.

Reading condition & movement terms

For mechanical watches, ask whether it’s been recently serviced and how accurately it’s keeping time. “要オーバーホール” (needs overhaul) signals a repair cost ahead.

Vintage caveats: servicing & water resistance

• Water resistance: old gaskets degrade — treat any vintage watch as not water resistant until serviced, regardless of the dial markings.
• Servicing: a vintage mechanical movement may run but still need a service to keep accurate time; budget for it.
• Originality of parts: dials can be refinished and hands/crowns replaced — ask what’s original.
• Quartz batteries: may ship dead or be removed for shipping rules; easy to replace.

Authenticity & “franken-watches”

For higher-end and luxury pieces, verify authenticity. Beyond outright fakes, watch for “franken-watches” — pieces assembled from mixed genuine and aftermarket parts. Ask for:

• Photos of the dial, caseback, movement and any serial/reference numbers.
• Confirmation of which parts are original vs replaced.
• Box and papers if relevant (adds value and confidence).
• A seller with strong ratings in the watch category for expensive buys.

Shipping, customs & cost

Total cost = item price + (domestic shipping) + proxy fee + optional services + international shipping + possible customs. Watches are small and light, so international shipping is modest — but use tracked, insured shipping for anything valuable. Importantly, customs duties on watches can be significant in many countries; check your rates before a high-value purchase, as duty is charged on arrival based on declared value.

Movements & accuracy explained

A watch’s movement is its engine, and it shapes both price and ownership. The three types:

• Automatic (自動巻き) — self-winds from wrist motion; runs while worn, stops after a day or two of rest. The collector favorite.
• Manual wind (手巻き) — you wind it by hand daily; common on older and dressier pieces.
• Quartz (クォーツ) — battery-powered, most accurate, lowest maintenance.

Set expectations on accuracy. A healthy vintage mechanical watch might run several seconds to a minute off per day — that’s normal, not a fault, and a service can improve it. Quartz keeps far better time. Useful things to ask a seller (a proxy can relay these): is it keeping reasonable time, what’s the approximate power reserve (how long it runs unworn), does it hand-wind and set smoothly, and has it been serviced recently? “稼働品” (running) means it ticks — not that it’s accurate or freshly serviced. For mechanical pieces, treat a future service as part of the cost, and you’ll avoid disappointment when a decades-old movement needs a tune-up to perform its best.
