Wristwatch company Baby-G shared on Thursday behind-the-scenes photos of K-pop girl band Girls' Generation in its beach-themed spring-summer campaign.

The idols singers drew attention from local media for their "sweet and sexy" image in their sixth campaign for the international watch range owned by Casio.

Yoona was described "as beautiful as though she has been drawn" and effusing a "goddess aura," while Sooyoung had “unrealistic model body proportions," according to Korean media outlets Thursday.

A Baby-G crew member said Girls' Generation aka SNSD, set to release the Japanese single "Catch Me If You Can" in April, displayed good teamwork and chatted amiably with staff throughout the photo shoot.

The company did not announce a specific release date for the upcoming watches.
