Look closely at the dial of the Seiko Lukia SSWA011J and you find clovers. At one o'clock and at seven, clover-shaped settings hold lab-grown diamonds, and the crown has been redesigned around the same motif so the detail carries round to the side of the case. Behind them, an embossed pattern of flowers opening sits under a transparent coating, polished to a metal finish — in a colour Seiko calls airy blue.
This belongs to Lukia's Happy Collection, which Seiko builds around a heart-lifting sparkle — watches meant to leave you feeling brighter each time you glance at your wrist. The Arabic numerals are rounded, drawn deliberately plump and playful, on a design Seiko first launched in 2011 and has kept evolving; this is the smaller version of it. The tonneau case measures 21.0mm across and just 7.0mm thick, the whole watch weighs 42 grams, and the tops of the bracelet and the curved sapphire glass are both gently rounded. Calibre 4N30 runs it, rated to 10 bar.

Why You'll Love It
- Clover-shaped settings at one and seven o'clock, each holding a lab-grown diamond. It is a far more considered way to place stones than spacing them evenly round the dial.
- The crown was redesigned on the same clover motif, so the idea does not stop at the dial edge.
- Airy blue is Seiko's own name for the colour, and the description it gives is relaxed and fresh — a lighter blue than a navy dress watch would use.
- The dial carries an embossed pattern of flowers opening, finished under a transparent coating and polished to a metal sheen, so the texture reads differently as the light moves.
- Rounded, almost balloon-like Arabic numerals. Seiko designed them to be playful on purpose — the point is that glancing at the time should lift your mood.
- A tonneau case, which is the barrel-shaped profile that curves along the wrist rather than sitting on it as a flat circle.
- 7.0mm thick and 42 grams complete. It clears a cuff easily and stops registering within the first hour.
- Real diamonds, grown in a laboratory rather than mined — the same crystal structure and the same sparkle, arrived at differently.
- The tops of the bracelet and the sapphire glass are both gently rounded, which is what gives the watch its softness in the hand.
- Curved sapphire with the anti-reflective coating on the inner surface, where knocks and scratches cannot reach it.
- About three years between batteries, ±15 seconds a month, and magnetic resistance built in.

Frequently Asked Questions
What is the Happy Collection?
A Lukia line Seiko builds around a heart-lifting sparkle — watches meant to colour a woman's everyday life, so that each glance at the wrist leaves a happy, positive feeling. On this reference that intention shows up in the rounded numerals and the clover-set diamonds rather than in anything heavy-handed.
What is the clover detail?
Two things, connected. On the dial, clover-shaped settings hold lab-grown diamonds at one and seven o'clock. On the side of the case, the crown has been newly designed around the same clover motif — so the detail carries from the dial round to the part of the watch you actually touch.
What are lab-grown diamonds?
Real diamonds, grown in a laboratory rather than mined. They share the crystal structure, the hardness and the way of handling light — what differs is the origin, not the stone.
What is the pattern on the dial?
An embossed pattern expressing flowers opening, pressed into the dial rather than printed on it. Seiko then covers it in a transparent coating and polishes it to a metal-dial finish, so the texture catches light and shifts as you move your wrist.
What does a tonneau case mean?
Tonneau is French for barrel, and it describes a case that is longer than it is wide with gently curved sides. It follows the line of the wrist rather than sitting on it as a flat circle, which is part of why a small watch like this one wears comfortably.
How long does the battery last?
Approximately three years. City Chain can replace the battery at any outlet, and it is worth having the case seals checked at the same time, since those are what maintain the water resistance over the years.
How accurate is it?
Seiko states an average monthly rate of ±15 seconds for Calibre 4N30 — a quarter of a minute a month at most, so checking it against your phone two or three times a year is enough.
Can I swim with it?
Yes. Seiko rates it at 10 bar with reinforced water resistance for daily use, which covers washing, rain and swimming comfortably. It carries no diver's designation, so it should not be used for scuba diving. Rinse it in fresh water after a pool or the sea.
How does 21mm wear?
Small, and deliberately. At 21.0mm wide, 29.2mm long and 7.0mm thick it reads as jewellery that tells the time, and the tonneau shape curves with the wrist rather than sitting flat across it. At 42 grams it is light enough to forget. It suits petite wrists particularly well. Any City Chain outlet can put it on your wrist.
Will it fit my wrist?
The bracelet is sized to a maximum wrist circumference of 176mm as supplied, and links can be removed to take it smaller. If your wrist measures above that, this is not the right reference — worth checking before you order.
Can the bracelet be adjusted?
Yes. Links can be added or removed within the bracelet's range, and the one-push triple-fold clasp opens on a button rather than a pin. City Chain offers complimentary bracelet sizing at any outlet; bring your warranty book along for the service.
What warranty does this watch come with?
The SSWA011J comes with a 3-year warranty when purchased from City Chain Singapore, an authorised Seiko retailer. Keep your warranty card and proof of purchase — both are required when submitting the watch for service.
