Seiko Lord Matic 5606-7260 – Suwa Seikosha (July 1973)

Fully revised in September 2025

The Seiko Lord Matic 5606-7260 is a classic model from the late production phase of the successful Lord Matic series by Suwa Seikosha .
In the early 1970s, this model series embodied the perfect balance between technical precision, everyday usability and elegant design – a watch for the discerning wearer who appreciates quality and understatement.

The centerpiece is the proven caliber 5606A , a fully automatic movement with 25 jewels , stop-seconds function , fast date and day change and manual winding function – a combination that at that time was reserved only for the higher-end Seiko series.

The deep blue cross-hatch finish dial with sharp-edged applied indices and recessed date frame and faceted hands conveys an elegant depth, while the original stainless steel bracelet with 'LM' signature on the clasp preserves the authentic character of the watch.

The watch was completely disassembled, cleaned, oiled, and regulated in September 2025. The movement runs precisely and reliably.
