Brand: Seiko Model: Lord Matic Reference Number: 5606-7150 Serial Number: 102107 Movement: Automatic Caliber 5606 Dial: Silver vertically brushed linen texture Case Size: 37 mm (excluding the crown) Case Material: Stainless Steel Production Year: October 1971 Condition: Excellent vintage condition Dial and Hands The highlight of this watch is the stunning silver dial, which features a vertical brushed texture often referred to by collectors as a linen finish. This texture catches the light beautifully and is in exceptional condition, free from blemishes or oxidation. The dial is furnished with raised, polished steel baton indices featuring black central inlays for contrast. The matching sword-style hands also feature black striping, ensuring high legibility. A framed day and date window is located at the three o'clock position, with Sunday displayed in red. The applied Seiko and LM logos remain crisp and bright. Case and Crystal The stainless steel case features the iconic monocoque "front-loading" construction, identified by the "Open Thru Glass" text on the caseback, which was designed to improve water resistance and structural rigidity. The case shape is a classic 1970s cushion design with smooth curves and short lugs. It remains in very well-preserved condition, retaining its original lines with only light surface scratches consistent with careful usage. The acrylic crystal is clear and presents well, offering an undistorted view of the textured dial. Movement Powering the watch is the renowned Seiko Caliber 5606 automatic movement, a 23-jewel mechanism that was a staple of Seiko's high-grade mid-tier offerings. This movement is known for its hacking and hand-winding capabilities. The watch is running within vintage tolerances, with timegrapher readings showing between -9 and -25 seconds per day, indicating a healthy movement offering reliable vintage performance. Strap The watch is paired with a new brown leather strap featuring a classic crocodile grain pattern. It is finished with a stainless steel buckle and provides a warm, elegant contrast to the cool tones of the steel case and silver dial. Condition This timepiece is in excellent vintage condition. The dial is pristine, which is the most critical factor for value in these references. The case shows honest signs of age with minor handling marks but no significant dents or deep damage. The movement is functioning correctly, and the overall presentation is clean and collector-grade. Dimensions The case measures 37 mm in diameter excluding the crown, a versatile size that wears prominently on the wrist due to the cushion case profile and dial-heavy design. Remarks The reference 5606-7150 is a quintessential model from the Lord Matic archives. Its combination of a monocoque case and a textured dial makes it stand out against standard flat-dial variants. It represents fantastic value for a vintage piece with significant horological history and timeless style. History Introduced in 1968, the Lord Matic (LM) line was positioned directly beneath the King Seiko and Grand Seiko lines in Seiko’s hierarchy. It was designed to offer high-quality automatic movements and sophisticated case designs to the upwardly mobile professional class of the era. The 5606 movement inside was one of Seiko's most successful calibers, bringing advanced features like hacking seconds and a bilingual day wheel to a wider audience, solidifying Seiko's reputation for mechanical excellence in the 1970s. / Second Vintage SKU: SEI1H76I2D000
