It is the rarest watch in this acquisition and is consistently listed on the international collector's market as hard to come by.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe case back is stamped with CASIO, the module number 827 in a box, the model designation TGW-10, as well as the inscriptions STAINLESS STEEL BACK, WATER RESISTANT, and JAPAN T. The dial is marked with CASIO, TRI GRAPH, and 10 BAR.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eWhen the digital watch imitated the analog watch\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eAt the beginning of the eighties, the matter seemed decided: the digital display was more accurate, cheaper, and feature-rich, while the analog watch was a dying breed. The only problem was that time could not be read as quickly on a digit field as it could on a watch face – a hand shows not just the time, but also how much is left.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eCasio's answer was the Tri-Graph. Instead of returning to mechanics, they recreated the watch face in the LCD: on the left, the hour runs as a hand graphic; on the right, the second as a rotating segment; and in the center sits the day-night indicator. It is an attempt to combine the advantages of both display types in one screen – and a historical document from the brief moment when the digital watch concerned itself with what it had just supplanted.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eDesign\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eA robust black resin case with distinct protective bars around the pushers, similar to those Casio developed in parallel for its sports watch lines. The four-screw steel back and the 10 BAR rating underscore its structural seriousness.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eOn the dial, three levels are layered: at the top, the three graphic fields with labels for SIG ON, ALM ON, as well as TIME, AM, PM, and SEC; in the middle, the large seven-segment field for time and date; and to the left of that, the function bar with ALM, DUAL, TMR, and ST.W. Below this, the lettering TRI GRAPH appears between two blue decorative lines.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eIn addition to the time display, the watch offers an alarm, second time zone, timer, and stopwatch function.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eDating\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe module number 827 points to the end of the 1980s; on the collector's market, the reference is predominantly dated to 1988. A day-accurate dating is not possible for Casio modules of this series without factory documentation; we provide this as an indication, not as a confirmed date.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eCondition and provenance\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe watch comes from Japan, where it was opened, inspected, and cleaned by a watchmaker, and fitted with a new battery. All three graphic fields and all functions work.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThis is a pre-owned original with signs of wear. All display elements are triggered correctly, and the graphic fields are complete. The main display has a warm, amber-colored hue – a sign of aging in the polarizing film, which regularly occurs in modules of this generation and does not impair readability. The plastic crystal shows fine scratches and slight haziness in the upper area. The resin case is free of cracks, and the pushers are complete and functional. The steel back shows fine signs of wear, all four screws are present, and the engraving is fully legible. The polyurethane strap is new.\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\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\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: Casio\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eModel: TGW-10\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eModule: 827\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eMovement: Quartz, digital (LCD), battery-powered\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eFunctions: Time, second, date, three graphic displays, alarm, second time zone, timer, stopwatch\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eCase: Resin with screwed stainless steel back\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eDiameter without crown: approx. 40 mm\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eHeight: 10.8 mm\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eLug-to-lug: 42.1 mm\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eLug width: 14 mm\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eWeight incl. strap: 27 g\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eDial: black with three circular graphic fields\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eStrap: new polyurethane strap\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eDating: \u003cstrong\u003ec. 1988\u003c\/strong\u003e\n\n\u003c\/li\u003e\n\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eProvenance: Japan\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eFor whom?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eFor collectors of digital Casio models beyond the reissued classics.
