Vintage Seiko Lord Matic (LM) (Ref. 5606-7150) – Newly Serviced

The Story and Condition
Immerse yourself in the classic elegance of early 1970s Japanese horology with this beautifully preserved Seiko Lord Matic. Based on the case back, this is the highly regarded reference 5606-7150, a model that perfectly exemplifies Seiko’s "Grammar of Design" from that era with its sweeping, C-shaped oval case and integrated-style lugs.

The immediate standout feature of this timepiece is its striking silver-grey dial, which boasts a delicate vertical brushed texture (often referred to as a hairline or linen finish). This subtle detailing catches the light beautifully, providing a dynamic backdrop for the polished, applied steel indices and the sharp handset. To ensure this incredible dial can be admired without distraction, a brand-new crystal has been installed during its restoration.

To complete the authentic vintage experience, this watch is fitted with its original LM-signed stainless steel multi-link bracelet. Original bracelets for the 5606 series are incredibly difficult to source in good condition, making this a fantastic, collector-ready package.

The Value of a Fully Serviced Movement
Powering this watch is the renowned Caliber 5606, a sophisticated 23-jewel automatic movement that features hand-winding capabilities and hacking seconds.

Buying a vintage 5606 unserviced can be a gamble, but this timepiece has been newly and thoroughly overhauled (as documented in the service photos). The entire movement was completely dismantled, meticulously cleaned, freshly lubricated, and expertly regulated. Crucially for the 5606 caliber, the quickset day (featuring English and Kanji options) and date functions operate flawlessly. By purchasing a freshly serviced watch, you are saving yourself significant time, hassle, and specialized watchmaker fees, ensuring your timepiece is mechanically sound and ready for daily wear.
