Seiko Westminster Chiming Quartz Clock Movement

This Seiko Westminster chiming movement is a high-quality quartz replacement designed for wall and mantel clocks that require traditional quarter-hour melodies and an hourly strike — without the complexity and maintenance of clockwork.

This is the identical movement I use for all customer clockwork-to-quartz conversions, including those detailed on ClocksUpcycled.co.uk. If you’re converting a mechanical chiming clock yourself, you’re using the same proven solution trusted in my own professional restorations and upgrades.

NOTE – if you are converting a clockwork clock to quartz and want to use the ORIGINAL hands – as I always do – you will need to consider either 1) adapting the existing hands to fit the Euro Fit shaft of this movement (as I do when customers send me their clock’s for conversion) or 2) SEND ME your existing hands and I will adapt them both to fit the Euro Shaft movement. The cost of this hand adaptation service is £35 including return delivery.

The movement offers a dual chime option, allowing you to select either the classic Westminster melody or the Whittington chime. It follows a 4 × 4 chime pattern, playing a partial melody every 15 minutes, a full melody on the hour, and then striking the hour count — preserving the character of a traditional chiming clock.

A built-in automatic night shut-off ensures the clock remains silent during selected hours, while a manual volume control lets you fine-tune the chime level to suit your room. The step-seconds motion provides accurate quartz timekeeping, making this movement both practical and dependable for everyday use.

Powered by a single LR14 (C-cell) battery, the movement is efficient and long-lasting. It is supplied complete with fittings and a quality audio speaker for straightforward installation.

Whether you’re restoring a vintage clock, converting a worn mechanical movement, or building a high-quality chiming clock from scratch, this Seiko unit offers the ideal balance of traditional sound and modern reliability — and it’s the same solution I confidently fit for my own customers.
