Questions about NK0023-57L
How is the NK0023-57L powered?
This is an automatic mechanical watch. Normal wrist movement winds a mainspring that powers the movement; it does not use a battery.
What if my NK0023-57L stops when I do not wear it?
An automatic can stop when its mainspring runs down while unworn. Restart and set it using the instructions for its caliber. Some automatic movements support crown winding and others do not, so check the manual before winding. Regular wear helps maintain the stored energy.
What is the difference between automatic and Eco-Drive or Solar?
Automatic watches store mechanical energy in a mainspring wound by wrist movement. Citizen Eco-Drive and Seiko Solar watches store electrical energy collected from light in a rechargeable cell. Wearing an automatic helps wind it; exposing a light-powered watch to light helps charge it. They need different care and restart routines.
Does my NK0023-57L need maintenance?
Yes. An automatic has moving mechanical parts and may need periodic servicing even though it has no battery. Check the manufacturer’s instructions for maintenance and movement accuracy. Contact our watch technicians if it repeatedly stops or runs unusually fast or slow after being properly wound.
What case size is the NK0023-57L?
The listed case diameter is 40 mm. Compare this with a watch you already wear. Case shape, thickness and the distance across the lugs also affect fit; a wrist photo is a visual reference rather than a guarantee of how it will fit your wrist.
What is the power reserve of the NK0023-57L?
The listed power reserve is Approximately 60 hours when fully wound. Actual running time depends on how fully the mainspring is wound and the movement’s condition.
What is the water-resistance rating of the NK0023-57L?
The listed rating is 50 meters / 5 bar / 166 feet. Use the manufacturer’s guidance for the activities suitable for this model, secure the crown before water contact and never operate it underwater. Gaskets can wear, so have water resistance checked before relying on it for swimming or diving.
How does the band on the NK0023-57L fit?
The listed band is Stainless steel. Contact our watch technicians for help checking fit before purchase. Professional bracelet sizing is complimentary. Contact our watch technicians about fit or visit an eligible St. Louis pickup location. Sized watches are excluded from standard returns; check the return policy before requesting sizing.
What complimentary extras are included?
A protective travel case is included with a qualifying watch purchase. Engraving is optional and complimentary where the watch’s design permits it. Your brand’s warranty and local support details appear above.
Where can my message be engraved?
Your selected engraving placement is subject to review. Glass casebacks or the watch’s design may prevent engraving in that spot. If needed, we’ll contact you to approve a suitable alternative, such as the clasp or back of a lug, before engraving.
Engraving adds 1–2 business days before shipment or pickup. Personalized watches are final sale for change-of-mind returns; damaged, defective or incorrect items follow our refund policy. Return details
