The closest alternative to the Isotope OVNI Jumping Disc The Neptunian is the Sartory Billard SB04-E ($3,609) — shared caliber (La Joux-Perret G101) and Visually similar. If price is the constraint, the Bulova Blue Dial Leather and Silicone Strap E1 Team Miami 96B460 at $550 (vs $3,044 for the OVNI Jumping Disc The Neptunian) covers most of the same brief. From the independents, the Xeric NASA Apollo 15 Moonphase is the standout microbrand take — visually similar and Solar. Stepping up, the Ming 37.09 ($6,900) is where the same idea goes with a bigger budget.
