Seiko Full Mechanical Service

Purpose: Get your Seiko back on spec for daily wear—without erasing its history.

What’s included (base)

  • Intake & diagnosis — functional check, timegrapher baseline, magnetism test; note your wear style and WR goal.
  • Complete teardown & ultrasonic clean — movement fully disassembled; case/bracelet deep-cleaned.
  • Parts included — new mainspring + new gasket set (where applicable).
  • Reassembly & lubrication — oils/greases to spec; end-shake/tolerances set.
  • Regulation & control — multi-position rate, amplitude, beat error; demagnetise if needed; power-reserve & autowind checks.
  • Testing — 48–72 h run test; pressure test where the case allows; log pressure + date.
  • Finish (patina-first) — clean only by default; light refinishing available on request.
  • Documentation — timing sheet + service notes; WR test card (if tested).

What’s extra (quoted & approved first)

High-value movement parts (e.g., balance assembly, pallet/escape, autowind components), crowns/tubes/pushers, hands/dial work, any crystal replacement, bezel/inserts, and light refinishing (only if you request it).

Water-resistance note

WR is valid at the time of test only. Wear, age and shocks can change it. If you actually swim/dive, we recommend annual checks.

€300,00
Calibre:


7S/4R €200. 6R €300. Base price includes a new mainspring and gaskets where applicable; big-ticket parts are quoted first.

Full teardown and ultrasonic clean; re-oil to spec; new mainspring + gaskets; multi-position regulation (rate, amplitude, beat error); demagnetise if needed; 48–72 h run test; water-resistance test where the case allows; timing sheet and notes. Patina-first: clean by default; light refinish only on request (extra).

Calibres covered: 7S, 4R/NH, 6R families and comparable mechanicals.


No. Crystal work (acrylic/mineral/sapphire) is separate and quoted. We’ll polish acrylic when feasible. If a damaged crystal prevents your WR target, we’ll advise and quote before continuing.

By default, no. We keep edges and brushing. Light, sympathetic refinishing is available on request and billed separately. No heavy polishing unless you ask.

We test and document WR at service. It’s valid at the time of test only. Annual checks recommended if you swim/dive.

However, user error may still allow water to get into the watch. Due to this, we offer no warranty for waterproofness - only a certificate that while in service in controlled conditions and no user error the watch has passed WR testing.


Typical 2–5 weeks. Order the service and choose a return-shipping option, complete the intake form, then ship your watch to us. We assess, confirm any extras, service and return it insured & tracked.
