An Underwater Treasure

The Seiko "Sea Urchin" is a desk diver that features a Seiko 7S36 23-jewel automatic movement. The case is polished on the sides and has light brushing on the lugs. The 42-millimeter stainless steel case has the classic dive watch barrel shape. The 120-click unidirectional rotating bezel comes in multiple colors for a subtle look or something more flashy. Rounding out the watch is its Hardlex crystal and display caseback.

Note: At checkout, choose between the SNZF15K1 and SNZF17K1 models, each of which is limited to 100 units.

Chunky Lumed Markers for Max Legibility

Luminous dot and block indicators make the watch extremely easy to read at a glance. The coating, in particular, really pops off the dark dial for a contrasting look. To keep track of the date, there's a window at the 3 o’clock position, which also shows the day of the week.

SNZF15K1 | Blue Dial, Pepsi Bezel, Stainless Steel Bracelet
