Seiko built LUKIA Grow around a flower. The motif is hypericum — yellow blooms in early summer, round plump berries by autumn — and Seiko gives the flower's meanings as sparkle, happiness and calm, set against a Spring and Summer theme of a flower garden. On the Seiko Lukia HEA002JJ you see it in the shape of things: a small case with soft lines, and a rounded crown modelled on the berry and sized to be easy to turn.
The movement is the other half of the story. Calibre 2R05 is what Seiko calls the smallest mechanical watch in Lukia — a self-winding mechanical in a 28.6mm case, where almost everything this size runs on a battery. It carries 21 jewels, holds roughly 40 hours fully wound, and can be wound by the crown to start it immediately. Roman numeral indexes sit under curved sapphire, there is a date, and at 68 grams and 11.4mm thick it disappears on the wrist. Rated to 10 bar.

Why You'll Love It
- The rounded crown is shaped after a hypericum berry — and because it is rounder, it is genuinely easier to turn than the fiddly crowns most watches this size are fitted with.
- A mechanical movement in a 28.6mm case. Seiko calls Calibre 2R05 the smallest mechanical watch in Lukia, and it is the reason this is not simply another small quartz dress watch.
- Nothing to replace, ever. It winds itself from your wrist, and the crown takes over when it has been off for a while.
- 21 jewels and roughly 40 hours of reserve, with a seconds-hand stop function so it can be set against an exact reference rather than approximately.
- Roman numerals carry the formality. On a small dress watch they do more work than batons or set stones would.
- The glass is curved sapphire with the anti-reflective coating on its inner surface — harder than mineral, and with the coating out of reach of scratches.
- A date window, which is not a given once a case drops below 30mm.
- 11.4mm thick and 68 grams complete, so it clears a cuff and stops registering after the first hour.
- Reinforced to 10 bar for daily wear — washing, rain and swimming are all within it.
- The one-push triple-fold clasp fastens with a button rather than a pin, which is quicker one-handed and more secure once closed.

Frequently Asked Questions
What is LUKIA Grow?
Lukia's classical, timeless mechanical line. Seiko frames it around growing and blooming, with a Spring and Summer theme of a flower garden, and it is the line that brought in Calibre 2R05 — described by Seiko as the smallest mechanical watch in Lukia.
What is the hypericum motif?
Hypericum flowers yellow in early summer and then sets round, plump berries through autumn. Seiko chose it as the motif for these watches and gives its flower meanings as sparkle, happiness and calm. The clearest place you see it is the crown, which is shaped after the berry.
What makes Calibre 2R05 unusual?
How small it is. Seiko calls it the smallest mechanical watch in Lukia, and that is what lets a self-winding movement sit inside a 28.6mm case. At this size quartz is the norm by a wide margin, so a mechanical movement here is a decision rather than a default.
How does the automatic movement work?
A weighted rotor inside the movement turns as your wrist moves, winding the mainspring. Wearing it through a normal day keeps it running. You can also wind it by hand using the crown, which Seiko shaped to be rounder and easier to turn — the quickest way to start it from cold.
What happens if I do not wear it for a few days?
It stops. The power reserve is approximately 40 hours from a full wind, so a watch set down on Friday evening will usually have stopped by Sunday. Wind it by hand, reset the time and date, and carry on. This is normal for a mechanical watch and does no harm.
How accurate is it?
Seiko states +45 to -35 seconds per day for this calibre. In practice most owners check it against a phone every week or two and adjust as needed. Accuracy varies with how the watch is worn, how much the mainspring is wound, and the position it rests in overnight. The seconds-hand stop function lets you set it against an exact reference.
Does it show the date?
Yes. Seiko lists a date calendar function alongside the hours, minutes and seconds, which is worth noting on a case this small — the space for a date window is not always there.
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, and have the case seals checked at service intervals.
How does 28.6mm wear?
Small and deliberately so. At 28.6mm wide, 34.5mm long and 11.4mm thick this is a compact dress watch that suits petite wrists particularly well, and at 68 grams it is light. It sits flat under a cuff and reads as jewellery as much as a watch. 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 178mm as supplied, and links can be removed to take it smaller. City Chain offers complimentary bracelet sizing at any outlet; bring your warranty book along for the service.
Does a mechanical watch need servicing?
Yes, eventually. A mechanical movement runs on lubricated moving parts that wear over years of use, so a service every few years keeps it running to specification and is also when the case gaskets are replaced. City Chain can arrange servicing through Seiko's authorised service network — bring your warranty book.
What warranty does this watch come with?
The HEA002JJ 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.
