The Story

The Citizen NJ0231-56L Tsuyosa Shore is the lighter, more coastal sibling in the Shore lineup. Where the NJ0230-59L goes deep navy, the 56L uses a marine blue sunray dial — brighter, more luminous, and more immediately summer. The colour-matched blue bezel insert and all-steel case keep the look clean and cohesive, and the sunray finish shifts the dial between vivid sky blue and a slightly deeper tone depending on the light. If the navy Shore is a blazer-and-denim watch, this one is a linen-shirt-and-loafers watch.

Underneath the colour, it's the same upgraded Shore platform: Calibre 8210 automatic movement with hacking function, 120-click unidirectional rotating bezel, sapphire crystal with date magnifier, exhibition caseback, and 100-metre water resistance. At 40mm with a 12.5mm profile and 149 grams on the integrated stainless steel bracelet, it wears identically to the rest of the Tsuyosa Shore family — mid-size, comfortable, and easy to forget you're wearing until someone asks about it.

Why You'll Love It

  • Marine blue is the lightest, most vibrant blue in the Tsuyosa Shore range — it reads as deliberately coastal and summer-forward, not corporate-navy. The sunray finish keeps it from looking flat by shifting tone with the light.
  • Same sport-capable Shore platform as the darker navy 59L — 100m water resistance, rotating bezel, sapphire crystal, hacking automatic movement — so you get genuine swim-ready functionality, not just beach-watch aesthetics.
  • The integrated bracelet creates a seamless case-to-wrist silhouette that makes the 40mm case look and feel sleeker than a standard lug-and-spring-bar design. No gaps, no visual breaks.
  • Exhibition caseback lets you watch the Calibre 8210 rotor and movement in action — a detail that adds perceived value well above the price point.
  • Sapphire crystal with anti-reflective coating and a date magnifier at 3 o'clock — the most scratch-resistant watch glass available, readable at a glance.
  • Hacking seconds function means you can set the time to the exact second — pull the crown and the seconds hand stops. A precision feature that cheaper automatics often skip.

Key Features

  • Citizen Calibre 8210 automatic movement — 21-jewel self-winding mechanical movement with approximately 40 hours of power reserve, hacking seconds function for precise time setting, and 21,600 vibrations per hour. No battery required.
  • 120-click unidirectional rotating bezel — marine blue aluminium insert colour-matched to the dial, with 120 precise click stops for elapsed-time tracking. Unidirectional rotation prevents accidental over-counting.
  • Sapphire crystal with date magnifier — anti-reflective sapphire rated 9 on the Mohs hardness scale with a magnifying lens over the 3 o'clock date window for easy reading.
  • 100-metre water resistance (10 BAR) — rated for swimming, snorkelling, and recreational water sports. Not rated for scuba diving.
  • Integrated stainless steel bracelet — seamless 3-link case-to-bracelet design with a fold-over clasp and hidden push-button release for a clean, secure fit.
  • Exhibition caseback — transparent glass caseback displays the automatic movement and oscillating rotor in action.
  • Luminous sword hands and lollipop seconds hand — wide sword-style hour and minute hands with luminous fill, plus a lollipop seconds hand for strong readability in low-light conditions.

Frequently Asked Questions

What's the difference between the 56L (marine blue) and the 59L (navy blue)?
Identical specs — same Calibre 8210, same stainless steel case, same sapphire crystal, same 100m water resistance, same weight. The only difference is the shade of blue. The 59L uses a deeper navy blue that leans more formal and versatile across wardrobes. The 56L uses a lighter marine blue that's brighter, more coastal, and more immediately summer. Both have colour-matched sunray dials and bezel inserts. Choose navy for year-round versatility; choose marine blue if you want a lighter, more expressive blue.
Which Tsuyosa Shore should I choose?
The NJ0230-59L (navy blue, all steel) is the most versatile and understated. The NJ0231-56L (marine blue, all steel) is lighter and more coastal. The NJ0234-58X (coral red, two-tone gold) is the most expressive. The NJ0232-53X (moss green, full gold) is the most luxurious. All four share the same case dimensions, movement, sapphire crystal, and 100m water resistance.
What's the difference between the Tsuyosa Shore and the standard Tsuyosa?
Both use the same Calibre 8210 automatic movement and integrated bracelet design. The Shore adds a 120-click unidirectional rotating bezel, upgrades water resistance from 50m to 100m, includes an exhibition caseback, and introduces larger sword-style hands with a lollipop seconds hand. The standard Tsuyosa is a pure lifestyle watch; the Shore is a sport-lifestyle watch with functional dive-timing capability.
What does "automatic" mean?
An automatic watch is powered by the natural movement of your wrist. A small rotor inside the case winds the mainspring as you wear it, so no battery is needed. If left unworn for about two days, it will stop and need to be set again — simply wear it or give the crown a few manual winds to restart.
What is the hacking function?
When you pull the crown out to the time-setting position, the seconds hand stops completely. This lets you synchronise the watch to a reference clock down to the exact second. Push the crown back in and the seconds hand resumes. Not all automatic movements offer this — the Calibre 8210 does.
How long does the power reserve last?
Approximately 40 hours when fully wound. This means the watch will keep running for close to two days after you take it off. Regular daily wear keeps it continuously wound.
Can I swim with this watch?
Yes. With 100-metre water resistance and a unidirectional rotating bezel, the Tsuyosa Shore is suitable for swimming, snorkelling, and recreational water sports. It is not rated for scuba diving. Avoid operating the crown while the watch is submerged.
Is the bracelet adjustable?
Yes. The stainless steel bracelet can be resized by adding or removing links. City Chain offers complimentary bracelet sizing at any outlet.
Is this a good gift?
The marine blue Shore is one of the most visually appealing watches in the Tsuyosa range — the lighter blue sunray dial has a warmth and liveliness that photographs well and draws compliments. Backed by sapphire crystal, an exhibition caseback, and a hacking automatic movement, it has substance behind the looks. Strong choice for birthdays, Father's Day, graduations, and milestone celebrations.
What warranty does this watch come with?
The NJ0231-56L comes with Citizen's official 1-year international warranty when purchased from City Chain Singapore, an authorised Citizen retailer.
