28mm

Reactor's #1 seller for three years in a row, Gamma's 45.5mm case makes a statement while still being very easy to wear. The heavy texturing is pure sport, backed up with an extreme 300M depth rating and an extraordinarily bright coating of Superluminova. Also available in a titanium model with Never Dark^® technology.

Oxide's 43.5mm case diameter puts it in a unique spot - as large as many of our men's models but with styling that speaks to the trend of larger watches for women. Oxide uses that size to effect with a svelte profile and accents of a whole new material in our line - high-tech ceramic, which composes the bezel and center links of the bracelet, giving those parts a beautiful but surprisingly scratch-resistant shine. Combined with a 1/20th second chronograph movement (another first in a Reactor Ladies' style), Oxide sets a new bar for sport fashion.
