Swatch says it adds four new watches to its SCUBAQUA collection on April 23, with sales starting online and in stores worldwide the same day.

According to Swatch, the new models came in aqua green, midnight blue, electric fuchsia, and solar orange. The company said the aqua green and midnight blue models included Swatch Pay for contactless payments in markets where the service was available.

Swatch said the watches were inspired by jellyfish and were designed for use below and above the sea. The company said the cases combined Bioceramic with biosourced material derived from castor oil.

According to Swatch, the watches had a crown at 10 o’clock, a transparent dial, a 44 mm case, glow-in-the-dark details, and water resistance rated to 10 bars. Swatch said the collection now had 9 diving watch models.

The company said the two Swatch Pay models would be sold online and in stores in markets where Swatch Pay was available and could be linked with payment cards from participating banks.
