CITIZEN NK0024-54X TSUYOSA 60 MECHANICAL MEN WATCH

The Citizen NK0024-54X Tsuyosa 60 is the version of the Tsuyosa that answers the two things owners kept asking for: more running time and a better bracelet. It replaces the standard collection's Calibre 8210 with the new in-house Calibre 8310, taking the power reserve from 40 hours to 60, and swaps the three-link bracelet for a five-link Jubilee-style design that sits far more fluidly on the wrist.

This is the two-tone variant — a silver-tone stainless steel case with a fixed gold-tone bezel and a bi-colour bracelet, with gold-tone hands and applied markers picking up the same warmth. The dial is a sunray green with a stamped guilloché-style texture, first introduced on the Tsuyosa small-seconds models and carried over here by demand. It gives the green far more depth than a flat sunray finish, and it is the reason this watch photographs better than it has any right to at 40mm.

The practical details are unchanged from what makes the Tsuyosa work: anti-reflective sapphire with a magnifier over the date, a crown recessed at 4 o'clock for a slimmer profile, a glass caseback showing the new movement, and 50-metre water resistance. At 40mm by 11.7mm and 129 grams, it wears the same as the rest of the family.

Why You'll Love It

• The 60-hour power reserve is the headline and it genuinely changes how you live with the watch. Take it off Friday evening, put it back on Monday morning, and it is still running at the right time — no resetting, no rewinding.
• The five-link Jubilee-style bracelet is new to the Tsuyosa line and it is a real upgrade. More links mean more articulation, so it drapes around the wrist instead of sitting across it.
• The guilloché-style stamped texture gives the green dial depth that a plain sunray finish cannot — the pattern catches light at different angles across the dial rather than sweeping uniformly.
• Two-tone is doing something specific here: gold on the bezel, bracelet and handset, silver on the case body. It reads warm and dressy without committing to a full gold watch.
• Green and gold is a naturally complementary pairing, and this is the only dial colour in the Tsuyosa 60 range offered in the two-tone finish.
• The Calibre 8310 is a new in-house movement rather than a carried-over one, with hacking seconds, hand-winding and a rated accuracy of -20 to +40 seconds per day, visible through the glass caseback.
• The crown is recessed at 4 o'clock, which keeps the case profile clean and stops it pressing into the back of your hand through a working day.
