Seiko called this system AGS – and the titanium version with 200 meters of water resistance is the most consistent application the series has found.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe case back is embossed with SEIKO TITANIUM, AIR DIVER'S 200m, reference 5M43-0B70, JAPAN J, and serial number 648060, and bears the Tsunami medallion that Seiko uses to identify its diver's watches.\u003c\/p\u003e\n\u003ch2 dir=\"ltr\" class=\"mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eAGS – Automatic Generating System\u003c\/h2\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eSeiko introduced the AGS in 1988. The idea solves the central annoyance of quartz watches: a rotor, like in an automatic watch, drives a micro-generator, the electricity generated charges a storage cell, and the quartz movement draws its energy from this. The watch thus needs no battery – only movement.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe AGS later evolved into the Kinetic line, under which Seiko continues to market the system today. The early AGS models are more interesting for collectors because they document the initial phase of the technology and because Seiko used them in the most demanding category: as diver's watches.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThis version combines the 5M43 caliber with a titanium case and 200 meters of water resistance according to diver's watch standards. At 12 o'clock, there is a power reserve indicator that is activated by a pusher – the seconds hand then jumps to the reserve scale and shows how much the storage cell is charged.\u003c\/p\u003e\n\u003ch2 dir=\"ltr\" class=\"mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eDesign\u003c\/h2\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe dial is deep black with a fine-grained, slightly matte surface that breaks reflections. Large, round luminous dots and wide bar indices are located at 6, 9, and 12 o'clock – legibility takes precedence over everything else here.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe hands are robustly dimensioned and fully covered with luminous material; the seconds hand is slender and white. At 3 o'clock, there is a framed double window for day and date, with the day of the week in two languages. The scales for power reserve and charge status are located at the top and bottom edges of the dial.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe titanium case is matte brushed and appears significantly lighter and warmer than stainless steel; with a diameter of 39.1 millimeters, the watch, including the titanium band, weighs only 85 grams. The unidirectional rotating diver's bezel has a strongly shaped toothing and clicks in minute increments. The watch is delivered with the original titanium bracelet with a signed folding clasp.\u003c\/p\u003e\n\u003ch2 dir=\"ltr\" class=\"mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eDating\u003c\/h2\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe serial number 648060 dates the watch to April 1996 according to the usual Seiko system. The first digit indicates the year, the second the month. This corresponds to the known production period of the 5M43 caliber.\u003c\/p\u003e\n\u003ch2 dir=\"ltr\" class=\"mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eCondition and Overhaul\u003c\/h2\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe watch was overhauled in Japan by a watchmaker in February 2026.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe dial is flawless: no moisture damage, no stains, the luminous dots are complete and evenly preserved. The hands are undamaged, day and date are neatly in the window, and the power reserve indicator works.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe glass is clear. The bezel shows significant signs of wear: there are several scratches on the scale surface, and abrasion is visible on the toothing. The titanium case has the fine scratches typical for this material, which are more pronounced on the matte surface than on polished steel. The titanium bracelet is complete and shows signs of wear on the links; the signed folding clasp closes securely. The crown and pushers operate smoothly, and the bezel rotates with defined resistance.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe actual condition is shown unretouched in the product photos.\u003c\/p\u003e\n\u003ch2 dir=\"ltr\" class=\"mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eTechnical Data\u003c\/h2\u003e\n\u003cul dir=\"ltr\" class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\"\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBrand: Seiko\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eModel: AGS Titanium Scuba 200 m\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eReference: 5M43-0B70\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSerial number: 648060\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eManufacturing date: April 1996\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eMovement: Seiko Caliber 5M43, AGS (Automatic Generating System), quartz regulated\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eFunctions: Hour, minute, central seconds, day (bilingual), date, power reserve indicator\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eCase: Titanium, unidirectional rotating diver's bezel\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eDiameter without crown: 39.1 mm\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eHeight: 12.9 mm\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eLug-to-Lug: 46.2 mm\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eLug width: 19 mm\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eWeight including band: 85 g\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eWater resistance ex-works: 200 m (Air Diver's)\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eDial: black, matte, with luminous dots\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBand: original titanium bracelet with signed folding clasp\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eOrigin: Japan\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eOverhaul: February 2026, overhaul in Japan\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003ch2 dir=\"ltr\" class=\"mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eFor whom?\u003c\/h2\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eFor collectors who want to trace Seiko's electronic history and go beyond quartz and Kinetic.
