Why this matters
Remember, a watch should sit comfortably on your wrist without sliding past the bone; the lugs should not extend beyond the edges of your wrist.

Key Buying Factors
01
Wrist Fit
Case diameter should not overhang your wrist. Measure your wrist circumference and use lug-to-lug length (usually 45-50mm for a 40mm case) to ensure the watch sits flat without pinching.
02
Strap Material
Leather straps mold to your wrist over time; stainless steel bracelets can be resized but may feel heavier. Consider NATO or fabric straps for a lightweight, adjustable option.
03
Movement Quality
Automatic movements are thicker (12-15mm) but offer craftsmanship. Quartz is slimmer (6-9mm) and more accurate. Evaluate your preference for mechanical interest vs. daily precision.
04
Style & Proportion
Dress watches under 10mm thickness suit formal wear. Dive watches with 14mm+ thickness and 44mm+ diameter make a bold statement. Match the watch's visual weight to your outfit.
Section 05
Care, Cost and Maintenance
Cleaning
Wipe the case and strap with a soft, lint-free cloth after each wear. For metal bracelets, use a damp cloth and mild soap, then dry thoroughly.
Winding & Maintenance
Wind automatic watches gently at the same time daily. Avoid overwinding. Service mechanical movements every 3-5 years to maintain accuracy.
Storage
Store watches in a cool, dry place away from direct sunlight. Use a watch box or pouch to prevent scratches. Consider a watch winder for automatics.
Pro tip
Measure your wrist in the evening when it is slightly larger, and bring a credit card to the store: if the card fits under the strap, the fit is too loose.
Frequently asked questions
How do I measure my wrist for a watch?
Use a flexible tape measure around your wrist just below the wrist bone. Record the circumference in inches or millimeters. This measurement determines the ideal case size range (typically 34-42mm for average wrists).
What if my wrist is very small?
Look for watches with a case diameter under 38mm and a lug-to-lug length under 46mm. Unisex or women's models often fit better. Avoid thick cases (over 12mm) as they can look bulky.
Does strap width affect fit?
Yes. The strap width should match the lug width of the watch (e.g., 20mm). A strap too narrow looks pinched; too wide won't fit. Tapered straps (20mm to 18mm at buckle) offer a more refined look.
How important is lug-to-lug length?
Extremely important. Lug-to-lug determines if the watch overhangs your wrist. It should be less than your wrist width. For a 6-inch wrist, keep lug-to-lug under 48mm for a comfortable fit.
