The Seiko 5 Sports SNZH57K1 is the black-and-gold reference of the SNZH series, introduced around 2010 and now discontinued. Enthusiasts nicknamed the series the "Fifty Five Fathoms" for its mid-century dive-watch styling: a glossy domed glass bezel insert, gilt hands and applied markers, and a warm black-and-gold palette that recalls the military divers of the 1950s. Of all the colorways in the family, the SNZH57 is the most popular and the most widely sought after, and the model has become one of the best-known custom bases in the Seiko modding community, which has kept demand strong long after production ended. Seiko has since revisited the design in its current 5 Sports line, but the original 7S36-powered SNZH remains the reference collectors look for. The 5 shield on the dial marks it as a Seiko 5, the line Seiko launched in 1963 to bring robust automatic day-date watches to everyday wearers. This example is the K1 export version and comes complete with its Seiko box, instruction sheet, hang tag and four spare links.
[Movement & Technology]
Seiko caliber 7S36 automatic movement with 23 jewels, beating at 21,600 vibrations per hour (6 beats per second) with a power reserve of approximately 41 hours when fully wound. The rated accuracy is +45 to -35 seconds per day. The 7S36 is wound by wrist motion only: it does not hand-wind and does not hack, so start it by swinging the watch gently from side to side before setting the time. Diashock shock protection and magnetic resistance of 4,800 A/m. The scratch-resistant Hardlex crystal is slightly domed, and the screw-down Hardlex exhibition caseback displays the movement and the Seiko-signed rotor.
[Functions]
Hours, minutes and central seconds. Day and date are shown together in the gilt-framed window at 3 o'clock, with the day in English and a second language. Crown at 3 o'clock: the first click sets the day and date, the second click sets the time. Unidirectional 120-click rotating bezel with an inverted-triangle marker at 12 and gilt numerals for timing elapsed minutes. Water resistant to 100 m (10 bar), suitable for swimming but not for scuba diving.
[Case & Bracelet]
Stainless steel case measuring approximately 42 mm (1.65 in) across excluding the crown, about 45 mm (1.77 in) including the crown, and about 13 mm (0.51 in) thick, with brushed and polished surfaces. Black domed glass bezel insert with gilt numerals at 10, 20, 30, 40 and 50 and a triangle at 12. Push-pull coin-edge crown at 3 o'clock. Screw-down exhibition caseback marked ST.STEEL, 7S36-04N0 and WATER RESISTANT 10BAR. Lug width 22 mm (0.87 in). Three-row stainless steel bracelet with brushed outer links and polished center links, closed by a Seiko-signed fold-over clasp with a flip-lock safety. Four spare links are included for sizing.
[Condition]
Very good used condition. The dial, hands, markers, bezel insert and crystal are clean and bright. The case is clean, while the bracelet and clasp show light hairline scratches and small scuffs from normal wear, most visible on the clasp cover.
