The short answer
The closest alternative to the Seiko Astron is the Seiko Astron GPS Solar 2025 Limited Edition ($2,900) — shared caliber (5X83) and Same family (Astron). If price is the constraint, the Tissot Supersport Chrono at $575 (vs $3,100 for the Astron) covers most of the same brief. From the independents, the AVI-8 Hawker Harrier Matador Chronograph is the standout microbrand take — common cross-shop and Racing chrono. Stepping up, the Grand Seiko SLGC001 ($14,700) is where the same idea goes with a bigger budget.
