Every Tissot Sideral watch incorporates a sturdy PVD-treated steel unidirectional bezel, complete with a luminous diving scale that ensures visibility even in low-light conditions. A key highlight here is the Sideral’s multi-colour lume, which employs distinct shades to illuminate the minute and hour markers along with the minute hand, creating a visually dynamic display. Available in three bold colour choices – blue, orange, and red – each design includes a matching minute track, except for the red model, which stands out with a distinctive grey one.
