Citizen has launched the $1,500 Attesa x The Mandalorian “Beskar” (AT8385-55E), a 42mm limited-edition chronograph that channels the franchise’s near-indestructible metal using Super Titanium. The watch is powered by Eco-Drive H800 movement and is limited to just 100 units worldwide.

Casio’s new G-Lide GBX-H5600-1 and GBX-H5600-2 surf watches add an optical heart-rate sensor with blood-oxygen readings while retaining the square, translucent GBX-100-inspired design and sunlight-readable MIP display. The pair launches in Japan in May for ¥44,000, with global availability yet to be announced.

Seiko expands its 1968 Heritage Diver’s line with the Prospex HBC001 (green) and HBC002 (black), pairing the Caliber 6R54 automatic GMT and largely unchanged styling with upgraded specs. The headline improvements are a new six-step micro-adjust clasp first seen on the Marinemaster and increased water resistance to 300 meters.
