Watches

A quartz movement usually uses a battery; a mechanical one may need manual winding or use motion through automatic winding. An automatic watch left stored may stop and require resetting. Solar charging is a power source, often for quartz watches, not a separate movement type; check its charging and storage instructions. Check the specific model's power system and the tasks involved if you rotate several watches. Do not infer accuracy or running time from the exterior's appearance.

Check thickness and the distance between the ends of the lugs too. A case may overhang a wrist despite a seemingly moderate diameter. Try its fit beneath a sleeve and check whether the crown presses when your hand bends. A strap needs suitable length and a manageable clasp; a metal bracelet may require link removal. Verify adjustment options and cost as well as the availability of compatible replacement straps.

Assess contrast between dial and hands, date size and reading ease without relying on an enlarged photograph. For water, a metre rating must not be interpreted as an unrestricted usable diving depth. Marketing labels and pressure ratings in bar or ATM do not by themselves establish suitability for showering, swimming or diving. Follow the manufacturer's permitted activities for that model and consider the condition of its seals. Do not operate crown or pushers underwater unless the instructions explicitly allow it. A diving-style appearance does not establish suitability for diving or swimming.

Ask about battery replacement, movement servicing and water-resistance checks where relevant. Crystal type influences handling, but does not remove the risk of damage. Clean case and strap according to their materials and avoid unapproved products. Leather needs different care from a metal bracelet, for example. A watch worn only occasionally still needs suitable storage and checks. Its purchase price does not summarise the ongoing care it may require.
