Why You'll Love It
- An ivory dial, which is an unusually light choice for a field watch and reads differently from the black and khaki the format usually gets.
- A 24-hour indication on the dial alongside the hour, minute and seconds hands.
- LumiBrite on the hands and hour markers, charged by light rather than drawing any power from the movement.
- A see-through case back, so calibre 4R34 is visible working from behind.
- It winds itself as you wear it, takes a hand wind when it has been sitting, and holds approximately 41 hours.

Frequently Asked Questions
What does the 24-hour hand show?
Seiko publishes the hand indicators for this reference as hour, minute, seconds and 24-hour, so there is a fourth hand reading against a 24-hour scale. Seiko does not specify a second time zone or GMT function for this calibre on its Singapore listing, so treat the hand as a 24-hour indication rather than assuming it tracks another zone.
How do I keep it running?
Wear it. Calibre 4R34 winds from the motion of your wrist, and holds approximately 41 hours once fully wound. Hand winding through the crown is available and is the quickest way to restart it after it has stopped. A mechanical watch that runs down comes to no harm — wind it, reset the time and date, and carry on.
Can I swim with it?
It is rated to 100 metres, which Seiko's guidance treats as suitable for swimming and for diving that does not use an air cylinder. It is not a diver's watch: the crown pulls out rather than screwing down, and Seiko does not give this reference its Diver's designation. The rating is a measured pressure, not a depth to go looking for, and the crown should never be operated while the watch is wet.
Is the dial readable in the dark?
Yes. Seiko applies LumiBrite to the hands and hour markers for this reference. It charges from daylight or indoor light and fades gradually through the night.
What can I see through the case back?
The movement. The case back is see-through, so calibre 4R34 is visible from the reverse, including the rotor turning as the watch is worn.
Does an automatic watch need servicing?
Yes. A mechanical movement runs on lubricated moving parts that wear over years of use, so periodic servicing keeps it running to specification. Bring the watch to any City Chain store for servicing.
Is the bracelet adjustable?
Yes. Links can be added or removed to size the stainless steel bracelet. City Chain offers complimentary bracelet sizing at any outlet — bring your warranty book along for the service.
