Invicta Force offers several lines of watches, automatic or quartz, that comfortably fit into sports and/or casual categories. Force timepiece contain chronograph, lefty chronograph, date, and multifunction complications; come in large (53mm) and medium (43 mm) sizes; include both ladies and men's models; and, incorporate a range of materials besides stainless steel: ceramics, mineral crystal, and titanium. These features make it a versatile master collection on par with such lines as Invicta II.

Invicta declare Force a “democratic” collection, and, appropriately enough, the idea of equality finds an outlet in the form of vertical symmetry: the left side of the case is outfitted with a crown that mirrors the right side. This additional crown rotates the bidirectional inner bezel, and lends the watches their unique, symmetrical, “democratic” look.

• Master Chrono (Midsize and Lady) features a 1/10 second chronograph encased in gold plated cases. The lugs carry a decorative screw (echoing the crowns) each; leather straps are the bands of choice for this line. Dials present a rather busy composition of three subdials and large, fat Arabic numerals – the subdials have been treated with an emphasis ring in the Midsize versions, where there's less space to discern the smaller details. Ladies watches employ classic pink and sea wave blue. A classic sports watch.

• Force Master Quartz brings a change in movement, substituting the automatic chronograph for a general purpose titular caliber. Less function means more space on the dial face, which Invicta chose to exploit by painting even larger and fatter Arabic numerals at the quarter hours, complementing them with matching enlarged hands. This is a casual watch with external sports characteristics, and not without hints at fashion awareness. Colors include white, blue, gold, brown, yellow, red, and more.

• Lefty Chronograph surprises not only by outer, but also inner differences from the two main lines discussed above. It's close to the Military line in design, and contains a rare quartz chronograph. A fixed tachymeter scale replaced the inner bezel, now reduced to a thin outer ring – both contributing to a functional “officer watch” look. Bright Arabic numerals immediately disclose this timer as a utility oriented tool.

• Force Military Quartz offers casual to formal aesthetic uncharacteristic of Invicta: purity of design, simplicity and seriousness dominate this line instead of the usual elaborate fun approach. Luminous long hands and clearly defined numerals draw all the attention, only the background color (orange and red especially) vying for more.
