Seiko - Sports 150 “Dancing Hands” – Chronograph Alarm...

Seiko Sports 150 “Dancing Hands” – Chronograph Alarm Timer – Blue Dial – 6M25-6000 – 1990s ____ DESCRIPTION An impressive and highly distinctive Seiko Sports 150 “Dancing Hands”, reference 6M25-6000, featuring a striking deep blue dial, stainless steel and gold-tone construction, and the fascinating multifunction quartz movement developed by Seiko during the 1990s. Commonly known among collectors as the “Dancing Hands”, this remarkable Seiko features an innovative multifunction quartz movement that automatically repositions its hands when switching between operating modes. This fascinating choreography of the hands is one of the most distinctive characteristics of Seiko's advanced quartz chronographs from the 1990s. Unlike conventional chronographs, this model features an unusual rotating crown that acts as a function selector. By turning the crown, the hands automatically move to display the selected function, creating the characteristic “Dancing Hands” effect. The Seiko 6M25 movement combines several complications, including a chronograph, countdown timer, programmable alarm and automatic calendar, all controlled through the crown and two pushers. Its large, sculpted case, decorative bezel, beautifully preserved blue dial and integrated two-tone bracelet give the watch a distinctive appearance characteristic of Seiko's ambitious sports collections of the period. A particularly interesting piece for collectors of vintage Seiko watches, Japanese quartz complications and the famous “Dancing Hands” series. ____ TECHNICAL SPECIFICATIONS - Brand: Seiko - Collection: Sports 150 - Commercial name: Dancing Hands - Model: Multifunction Chronograph Alarm Timer - Reference: 6M25-6000 - Movement: Seiko Calibre 6M25 - Movement type: Japanese quartz - Production period: Approximately 1990s - Case diameter: Approximately 43.5 mm excluding crown, measured across the widest part of the case - Bezel diameter: Approximately 40.6 mm - Case material: Stainless steel with gold-tone accents and base-metal bezel - Dial: Original deep blue dial with gold-tone details - Crystal: With magnifying lens over the date - Bracelet: Seiko stainless steel and gold-tone bracelet - Bracelet length: Approximately 14 cm - Suitable wrist circumference: Approximately 18.5 cm, including the watch case - Clasp: Original Seiko folding clasp with adjustment holes - Case back: Stainless steel, screw-down - Original water-resistance rating: 150 metres / 15 bar - Functions: Hours, minutes, seconds, date, month, chronograph, split-time measurement, countdown timer and alarm Water resistance has not been recently pressure-tested and is therefore not guaranteed. ____ THE FAMOUS “DANCING HANDS” MOVEMENT – SEIKO CALIBRE 6M25 The main attraction of this watch is undoubtedly its fascinating Seiko 6M25 multifunction quartz movement, popularly known as “Dancing Hands”. The nickname refers to the unusual way in which the watch hands automatically move around the dial when changing between different operating functions. Instead of incorporating multiple conventional chronograph subdials, Seiko developed an innovative system in which the main hands perform different functions depending on the operating mode selected. Rotating the crown causes the hands to move automatically to their corresponding positions, sometimes travelling rapidly around the dial in a movement resembling a dance. This distinctive behaviour is entirely intentional and represents one of the most fascinating characteristics of Seiko's multifunction quartz technology. The small indicator positioned at 6 o'clock identifies the selected function. The movement features six operating positions: - TIME: Standard timekeeping with the alarm disengaged. - ALM.ON: Standard timekeeping with the alarm activated. - ALM.SET: Setting and checking the alarm. - TIMER: Countdown timer. - CHRONO: Chronograph. - DATE/MONTH: Calendar display. The movement also features a date aperture at 3 o'clock and a peripheral month scale surrounding the dial. ____ OPERATING INSTRUCTIONS – CROWN AND PUSHERS IMPORTANT: This watch operates differently from most conventional quartz chronographs. The gold-tone crown at 3 o'clock is primarily used to select the operating mode, rather than directly adjusting the hands. The two pushers located on the opposite side of the case control the different functions. - Upper pusher: Button B - Lower pusher: Button A 1. SELECTING THE OPERATING MODE With the crown in its normal position, rotate it clockwise or counterclockwise. The small hand in the subdial at 6 o'clock moves to indicate the selected operating mode. Depending on the selected function, the main hands automatically move to their corresponding positions. This characteristic movement of the hands is precisely what gives the watch its famous “Dancing Hands” nickname. It is an intentional feature of the Seiko 6M25 movement and should not be confused with a malfunction. 2. SETTING THE TIME - Rotate the crown until the mode indicator points to TIME or ALM.ON. - Pull the crown out to its setting position. - The seconds hand automatically returns to 12 o'clock. - Press the upper pusher (B) to advance the minute hand. - Press the lower pusher (A) to advance the hour hand. - Check the correct AM/PM setting, as this also affects the date change. - Push the crown back into its normal position when the desired time has been set. Holding a pusher allows faster adjustment. Unlike a conventional watch, the time is adjusted using the pushers rather than by rotating the crown. 3. CHRONOGRAPH FUNCTION The chronograph measures elapsed time up to 60 minutes with an accuracy of 1/10 of a second. - Rotate the crown until the indicator points to CHRONO. - The main hands automatically reposition themselves for chronograph operation. - Press the upper pusher (B) to start timing. - Press B again to stop timing. - Press the lower pusher (A) to reset the chronograph. The chronograph also supports split-time measurements: - Press B to start. - Press A to display an intermediate time. - Press A again to resume the running-time display. - Press B to stop. - Press A to reset. The movement uses the main hands to indicate the elapsed minutes, seconds and tenths of a second. 4. COUNTDOWN TIMER The watch includes a programmable countdown timer of up to 60 minutes. - Rotate the crown to TIMER. - Ensure the hands are in their zero positions before setting the countdown. - Press the lower pusher (A) to select the desired countdown duration in one-minute increments. - Press the upper pusher (B) to start the countdown. - Press B again to pause or resume. - After stopping the timer, press A to reset. At the end of the countdown, the watch is designed to emit an audible signal for approximately five seconds. 5. ALARM FUNCTION The Seiko 6M25 incorporates a programmable alarm operating on a 12-hour cycle. To set the alarm: - Rotate the crown until the indicator points to ALM.SET. - The main hands automatically move to display the programmed alarm time. - Press the upper pusher (B) to adjust the minutes. - Press the lower pusher (A) to adjust the hours. To activate the alarm: - Rotate the crown to ALM.ON. To deactivate the alarm: - Rotate the crown to TIME. The alarm is designed to sound for approximately 20 seconds when the programmed time is reached. Pressing either pusher stops the alarm sound. 6. CALENDAR AND MONTH DISPLAY The watch incorporates an automatic calendar with a particularly interesting month indication system. - Rotate the crown to DATE/MONTH. - The main hands automatically reposition themselves to point towards the corresponding month on the peripheral calendar scale. - The date is displayed numerically through the aperture at 3 o'clock. To adjust the calendar: - Select DATE/MONTH. - Pull the crown out. - Press the upper pusher (B) to adjust the month. - Press the lower pusher (A) to adjust the date. - Push the crown back into its normal position. The calendar automatically accounts for months of different lengths, although manual correction is necessary for February in leap years. The unusual hand movements when changing modes are part of the original design of this multifunction Seiko movement. ____ CONDITION Very good vintage condition.
