Seiko's four new mechanical Speedtimers priced in the US, undercutting UK and EU tags
Seiko has listed all four new Prospex Speedtimer mechanicals on its US store, starting at $950. The HBC003 and HBC004 skip the chronograph entirely, using a second crown at 4 o'clock to drive an inner countdown ring, and both carry a 72-hour 6R55.
