*Running seconds sub-dial located at the 6 o'clock position.
*Tachymeter scale on the inner bezel flange.
*Water Resistance - using a revolutionary patented design which relies on a butterfly collar around the pushers & crown. These external butterfly collars turn a 1/2 turn clockwise & counter-clockwise (independently of the crown & pushers) which clamp down & compress gaskets to ensure water resistance. Each collar has indicating arrows to easily discern if the watch is currently securely water resistant.
*Features the JLC quick-change strap system so that straps may be changed in seconds by the means of a quick-release button on the back of the case. The watch is NOT supplied with an additional strap.
