SEIKO SUR354P1 QUARTZ TWO-TONE GOLD DIAL WOMEN WATCH

What is the right way to change the date and the weekday?

Draw the crown to its middle stop. From there, rotating it in one direction advances the date and rotating it the other way advances the weekday; set each one position short of the figure you are aiming for. Then pull the crown right out and carry the hands forward until the date and weekday you want turn over together, which also confirms the watch is reading the correct half of the day. Set the time, then press the crown back. Seiko's general instructions for analogue watches warn against altering the calendar between 9:00 pm and 4:00 am. The reason stated is the whole of it: the calendar may not change properly if altered then. Because Seiko issues no manual of its own for calibre 6N33, that window comes from its general analogue guidance rather than from any document specific to this movement — but the remedy does not change: run the hands clear of those hours first, then set the calendar.

Does it need to come off for water?

Not for anything ordinary. Seiko's general guidance for a 10 bar watch reaches as far as bathing and shallow diving, so hand-washing, a shower, a swim and any amount of rain are all well inside the rating, and nothing on the watch objects to getting wet. The exception is scuba diving, which Seiko excludes at this level and refers instead to its Diver's range; and the 100-metre figure is a tested pressure rather than a depth. Three habits keep it reliable: press the crown fully home before going anywhere near water, never work the crown with the watch wet or lathered, and rinse the case off afterwards if it has been in salt water or a chlorinated pool.

Is the dial visible at night?

Not without a light on. Seiko specifies no luminous material for this reference. Without a coating to charge up, neither the hands nor the batons carry any glow, and the dial vanishes the moment the room does. This cannot be added later, so it is a point to settle in advance. A reference listing LumiBrite is the choice for anyone who needs the time readable in the dark.

What kind of crystal is over the dial?

Sapphire, synthetically grown for the job and one of the hardest materials fitted to a watch. Hardness here means resistance to the incidental contact nobody notices at the time — sleeves, bag handles, doorframes. The limitation is worth stating plainly: hard materials resist scratching but not impact, so a sharp strike against stone or a tiled floor can still chip the crystal. Ordinary care is all it asks.

What is the battery life, and is there any warning before it stops?

Seiko rates the battery at approximately three years. Many of its quartz watches do give a warning: the seconds hand begins advancing in two-second steps rather than ticking once per second, and the time stays accurate while that happens. Seiko notes the feature is not built into every movement, so treat it as useful if it appears rather than something to rely on. Bring the watch to any City Chain store for servicing. The screwed back has to be lifted and re-tightened onto an intact gasket, and if that is done badly the 10 bar rating is simply gone.

How does it sit on the wrist, and can links be removed?

The figure that governs the fit is the 37.5mm distance between lug tips, because that is what has to lie across the wrist; the 29.8mm diameter describes the dial only. Depth is 8.5mm, the bracelet is 14mm wide where it meets the case, and the watch weighs 67g complete. Yes, links can be taken out to shorten the bracelet. City Chain offers complimentary bracelet sizing at any outlet, and it is worth bringing your warranty book along.

What cover comes with the watch?

Three years against manufacturing defects, on any SUR354P1 bought from City Chain Singapore as an authorised Seiko retailer. The cover addresses faults built into the watch. It does not reach damage from a knock or a drop, the wear a case and bracelet pick up over years of use, or a battery that has run its course. Warranty work needs the card and the receipt presented together, so keeping the two filed in one place from the start saves trouble later.
