Casio G-Shock & Baby-G Couple 25th Anniversary G Presents Lover Collection's Limited Models LOV21A-1A LOV-21A-1A [Couple Watch Set]

Celebrate your timeless love with limited edition matching G-SHOCK and BABY-G watches inspired by the mathematical formula for love. The G Presents Lover’s Collection marks its 25th anniversary with an extra-special pair of holiday timepieces.
What better symbol of romance than a one-of-a-kind design featuring the equation x²-|x|y+y²=25, which, when plotted out, creates a heart-shaped graph symbolizing everlasting love? This unique take on the classic oversized GA-100 and its smaller mate, BA-110, feature watchbands in a blackboard design filled with math formulas. These equations hide a romantic secret that just you and your special someone share — align the bands to bring the two halves together to complete a single heart.
The star at the 25-minute mark signifies the 25th anniversary of this special collection, while the case back is engraved with the year 2021, as well as with an angel and devil, because we know how opposites attract.
Packaged in a special two-watch box in black, these timepieces make an unforgettable gift.
