Citizen’s Summer-Ready Promaster Diver Runs 12 Months in the Dark and Costs Just $450

For decades, the answer to “which is the best affordable dive watch” began and ended with Seiko – and we love Seiko. But somewhere between the beloved SKX (we still wear ours regularly) being cut and Prospex prices slowly rising, the Citizen went from being a perennial runner to a brand enthusiasts are starting to recommend more often.

Scroll through any viewing platform this week and it’s hard to miss the feeling. Citizen continues to hedge in the budget dive space, and just in time for summer, it’s back with three updated Promaster Dive models.

Small Case, Same DNA

The new indicators reduce the case to a 40.6mm stainless steel package, a welcome cut considering that Citizen’s core Promaster divers have hovered around 44mm for years (to say nothing of the 48mm “Eco-Zilla”). The rest of the formula remains unchanged, with 60 clicks of the unidirectional bezel, screw-down crown, and lume hands and markers used.

You also get a light-resistant sapphire crystal and ISO-certified 200m water resistance, which is a multi-tool watch for $450. Seiko Prospex solar divers, a clear shop, start north of $500 and drop down and finish at that price.

A Year in the Dark

Citizen’s new Eco-Drive Caliber E118 replaces the outgoing E168, and extends the battery life from nearly six months to a full year on a single charge of light energy. Accuracy is +/- 15 seconds per month, which is impressive for something that doesn’t require a battery.

The improved performance of the E118 also allows more light to pass through the solar cell, meaning Citizens can use a brighter dial than previous Eco-Drive watches.

Summer Colors (Japan’s Last Best)

Speaking of that white dial, that might be a trashy choice, pairing a black bezel with an orange seconds hand and a green strap. There’s also a blue gradient dial with the same bezel and a killer black version for traditionalists.

All three ride ropes made of BENEBiOL, a plant-derived urethane developed by Mitsubishi Chemical that is more durable and flexible than petroleum-based materials. As for the fourth color, a black dial with an orange bezel and strap? Japan is special, naturally. Some cultures never die.

Citizen Promaster Dive BN0265, BN0266 & BN0267

Citizen adjusts its $450 diver down to 40.6mm and drops to a new Eco-Drive mechanism that takes a full year on a charge, with a white dial, olive strap variant that steals the show.
