The reversal of time becomes reality

Retrograde mechanism refers to jumping back to the starting point after having reached the end, making its movement a reciprocating motion different from the common circular motion.

Traditional watches always move in a circle around the center point. As early as 1794 Abraham-Louis Breguet made a pocket watch with retrograde date display. E. Koehn exhibited his own retrograde second hand patent in 1892. Ever since 1903 when Giovanni Sgherlino registered retrograde hour and minute hand patent in Switzerland, retrograde has diversified into a variety of functions.

The retrograde mechanism researched and developed by Tianjin Seagull Watch Company was awarded China National Patent in 2005. Sea-Gull retrograde watch series not only have contributed innovative ideas to the retrograde technology, but also provided new products for watch fans who are fond of retrograde features.

Sea-Gull M171S automatic flying wheel watch is a popular model among watch fans, attributable to the following three success factors.

1)    Highlight practical functions. Besides hour, minute and second, there is a retrograde month date display at 10 o’clock position. The other retrograde week day display is at the 2 o’clock position.

2)    The mechanical movement is demonstrated in front of eyes. At 6 o’clock position is a hollowly-designed framework, within which a balance wheel is running non-stop to add mechanical dynamics.

3)    For watches with double retrograde windows, a tiny error in dial layout will affect the overall visual effect. The success of this watch’s creative and clean dial design lies in the perfect reflection of symmetrical aesthetics. Although there are five hands on one dial, the readings of all parameters are not affected at any given time. The unique formation of two fan-shaped retrograde displays, blue hands in contrast with silver grey white dial, echoing with the flying wheel, signify the soul of M171S.
