King Seiko, one of the most prestigious names in the vintage watch world, is the strongest representative of Seiko's golden age, challenging Swiss chronometer standards. The model we are reviewing, reference 5626-7041, is not just a watch, but also an engineering marvel with the title of "Officially Certified Chronometer." One of the most refined examples of the 56KS series, this piece embodies the brand's philosophy of high precision and superior craftsmanship in a single body.
Case Design and Wrist Comfort
The watch's 36 mm (with a majestic appearance of 41.7 mm including the lug on the measuring device) stainless steel case is designed in accordance with the "Grammar of Design" principles. Its sharp lines, polished surfaces, and brushed texture reflect light perfectly. The iconic "KS" logo on the crown and the slim profile of the case create a very balanced and extremely elegant look on the wrist. The sapphire crystal-like clarity of the glass highlights the strong lines of the case.
Dial Details and Condition
The "Chronometer Officially Certified" inscription on the matte white dial confirms that this watch is much more than just an ordinary automatic timepiece. The day and date window at 3 o'clock retains its vintage Seiko character with blue Saturday and red Sunday details. The application indices and razor-sharp hands offer excellent readability even with the slightest light leakage. The "Hi-Beat" and "Suwa" emblems at the bottom of the dial indicate the high-beat nature of the movement.
