The Most Comprehensive Range of Seiko Parts Available

Seiko is one of the most widely serviced watch brands in the world, and for good reason. The brand's commitment to in-house manufacturing means that genuine parts are available for an exceptionally broad range of models and calibres, spanning decades of production. At WatchPlaza, we stock genuine Seiko replacement components for current production models as well as a significant range of older and vintage references, including parts that are no longer available through mainstream distribution channels.

Whether you are carrying out a routine service, restoring a vintage piece, or sourcing a specific component for a calibre no longer in production, our catalogue is one of the most comprehensive available from an independent retailer.


Parts for Every Seiko Calibre

Seiko has produced dozens of in-house calibres across quartz, automatic, solar and Spring Drive technologies. Many of these movements have remained in production for years or decades, making genuine parts widely available for servicing. Well-known calibres such as the NH35, NH36, 7S26, 6R15, 6R35, 4R36 and the older 7009 and 7002 series are all represented in our catalogue, with components ranging from complete movements to individual stems, crowns and gaskets.

For each part in our catalogue, compatibility information is listed by model number, case number and calibre reference, allowing you to identify the correct component before ordering.


What We Stock

Our Seiko parts catalogue covers the full range of components needed for servicing, restoration and customisation.

Movements and Movement Parts

Complete movements and individual calibre components, including rotors, setting levers, keyless works and technical parts for a wide range of Seiko automatic and quartz calibres.

Dials and Hands

Original Seiko dials and hand sets for current and older models. Hands are listed by calibre compatibility and include hour, minute and second hands across a wide range of finishes and specifications.

Crystals

Mineral and sapphire crystals for Seiko models across the Prospex, Presage, Seiko 5 and vintage ranges. Crystals are listed with dimensions and model compatibility.

Cases, Case Backs and Bezels

Complete watch cases, case backs, bezel inserts and chapter rings. These components are listed with full model and calibre compatibility information to ensure correct fitment.

Crowns, Stems and Keyless Works

Original Seiko crowns and stems for current and older calibres. Correct crown and stem matching is critical for water resistance and movement function, and our listings include full calibre references.

Straps, Bracelets, Clasps and Links

Original Seiko straps and metal bracelets, together with individual links, clasps, deployant buckles and end pieces. Listed by lug width and model reference.

Gaskets and Seals

Case back gaskets, crown gaskets and crystal gaskets for a wide range of Seiko models. Essential components for maintaining water resistance after a service or case opening.

Small Parts

Spring bars, case pins, screws, pins and batteries. These components are stocked for a wide range of current and older Seiko references.


Discontinued and Hard-to-Find Seiko Parts

One of WatchPlaza's key strengths is our stock of discontinued Seiko parts, covering components that are no longer available through standard distribution. As Seiko continues to develop new models and retire older ones, sourcing parts for vintage and out-of-production references becomes increasingly difficult.

We maintain an active archive of discontinued components, including parts for calibres and models that have been out of production for many years. If you are restoring a vintage Seiko or servicing a model with limited parts availability, our catalogue is a reliable first stop.

If the specific part you need is not listed, contact us directly. In many cases we are able to source components through our supply network, though availability and lead times vary.


For Watch Enthusiasts and Professional Watchmakers

Our catalogue serves both professional watchmakers carrying out full service work and watch enthusiasts maintaining or restoring their own pieces. Product pages include compatibility information, dimensions and specifications to support accurate part identification before ordering.

Professional installation by a qualified watchmaker is recommended for movement components, gaskets, crystals and any parts that affect water resistance or timekeeping function.


About Genuine Seiko Parts

Genuine Seiko replacement parts are manufactured to the same specifications as the original components installed at production. Using genuine parts helps maintain the intended fit, function and reliability of the watch, and is particularly important for components that affect water resistance, timekeeping accuracy or movement integrity.

WatchPlaza stocks genuine Seiko parts sourced through established supply channels. If you have questions about the compatibility or specifications of a specific part, feel free to contact us before ordering.
