A few terms that will come up when you start:

The movement, or calibre, is the engine of the watch, made up of springs, gears, and other mechanical parts.

A hand-wound watch is powered by turning the crown yourself, usually once a day. An automatic winds itself through the movement of your wrist, but will stop if left unworn for a day or two.

Power reserve refers to how long the watch will run once fully wound.

Complications are any functions beyond basic timekeeping, such as a date display, chronograph, or second time zone.

Jewels are are synthetic rubies used as bearings inside the movement that reduce friction and help it run smoothly.

For most wrists, 38–42mm works well. If your wrist is under 7 inches, 38–40mm is usually a safe range. Larger wrists can wear 42mm and above more comfortably.

However these are guidelines, not rules. Case shape, dial design, and strap width all change a watch’s visual balance and presence on the wrist. Thickness has a direct impact on comfort and wearability as well.

If you plan to wear a watch every day, it is best to try it on before you buy. Photos often flatten the case and can make the proportions look misleading.

At the entry level, you’ll typically come across movements from three manufacturers:

At the mid-range and above, you will start seeing in-house movements — calibres designed and made by the brand itself. Many brands treat this as a mark of credibility and technical strength. That said, an in-house movement reflects manufacturing control; and not always guaranteed leap in performance.

A well-finished ETA may outperform a poorly executed proprietary movement.

What matters most in a first watch is how practical the movement is to live with. Does it hack, so the seconds hand stops when you set the time? Can it be hand-wound, so you can get it running easily after it has been sitting still? How much power reserve does it offer once fully wound?

Most mechanical watches belong to the following broad categories:

Dress watches are slim, simple, and suited to formal or business settings. They are usually time-only, with clean dials, restrained proportions, and leather straps.

Field watches have military roots and are built for legibility, durability, and everyday use. They are typically 38 to 40mm, with Arabic numerals, matte dials, and canvas or leather straps.

Dive watches are built for water resistance and usually feature a unidirectional rotating bezel to track elapsed time. They tend to be thicker and heavier, with luminous markers for low-light visibility.

Pilot watches, or Fliegers, have large, high-contrast dials designed for cockpit legibility. The two main styles are Type A, with large numerals, and Type B, with an inner minutes ring and outer hours track.

Chronographs have a built-in stopwatch function operated by pushers on the side of the case. These are thicker and busier on the dial, with subdials for elapsed time.

For a first mechanical watch, a field watch or a dive watch is the most versatile choice. Both are durable, legible, and easy to wear in most settings.

When buying a new watch, it’s best to go with authorised dealers or brand boutiques that offer warranty and authenticity. In India, retailers like Ethos, Zimson, and Helios offer a broad selection of major brands. For Japanese watches, Amazon and direct importers often have competitive pricing.

When buying pre-owned, choose sellers with a strong reputation and clear feedback. Good places to look include watch groups, forums, and local watch meets.

Try the watch on before buying whenever possible. Check how it sits on your wrist, how it feels under a shirt cuff, and whether the crown winds smoothly.

The strap changes the character of a watch more than you might expect.

Metal bracelets add weight and give a watch a more formal presence. They are durable and practical, but quality can differ sharply. A well-made bracelet feels solid, with secure end links and a dependable clasp. A weaker one feels thin, and rough in motion.

Leather straps are classic and comfortable, and they’re well suited for dress and field watches. They age with use and absorb moisture, which makes them less practical for daily wear in humid climates.

NATO and canvas straps feel casual and light; alongside being simple to swap.

Rubber and silicone straps are great for dive watches and active wear. They are water-resistant, easy to clean, and now available in much better quality across price points.

Most watches use standard lug widths like 18mm, 20mm, or 22mm, so replacement straps are easy to find. Getting a new strap is one of the simplest ways to give a watch a different character without buying another one.

Wind a hand-wound watch once a day, ideally at the same time, and stop when the resistance feels firm. An automatic will usually keep itself running with regular wear, and if it stops, you can simply set it and wear it again.

Keep mechanical watches away from strong magnets, which can affect timekeeping. Service them every five to seven years, and store them in a cool, dry place when not in use. A simple watch box is enough; a winder is useful, but not essential.

Spend a little time with a mechanical watch — you’ll begin to notice accuracy, movements, references, and the details that shape your taste. That is often how a collection starts: one watch, then a deeper interest in the next.
