The idea behind a “watches every man should own” list is not really about collecting. It is about function. These are the watch types every guy needs — and the person who has explored all of them tends to wear their watches with a lot more intention than the person who has owned just one. Here are seven categories, one watch from each, covering almost every situation your wrist will encounter.
1. The Diver: Seiko Prospex Automatic 200m (~$450)
A diver is the most practically useful watch you can own. It does everything — casual, sporty, travel, beach — without ever feeling out of place. The Seiko Prospex 200m automatic runs the Cal. 4R35, hacks and hand-winds, keeps 41 hours of power reserve, and delivers 200m of water resistance with a unidirectional rotating bezel in a 44mm case that tends to disappear on the wrist. Hardlex crystal means it is not precious. Use it accordingly. Most people who buy one as their first diver find it is also one of the last watches they ever want to take off.
2. The Dress Watch: Orient Bambino V2 (~$200)
Every collection needs a watch you would wear to a wedding or a job interview without apology. The Orient Bambino V2 does this at a price that makes the decision painless. The Cal. F6724 is automatic with 21 jewels, hand-winds, hacks, and delivers a 40-hour power reserve in a 40.5mm case with a domed mineral crystal that catches light exactly the way a dress watch should. At $200 it is one of the most honest value propositions in watchmaking.
3. The Field Watch: Hamilton Khaki Field Mechanical 38mm (~$495)
Field watches exist because soldiers need to read time quickly under stress. That design philosophy has never gone out of style. The Hamilton Khaki Field Mechanical is a direct descendant of Vietnam-era MIL-SPEC watches, powered by the hand-wound Cal. H-50 — 17 jewels, 21,600vph, 80-hour power reserve. A sapphire crystal covers an immediately legible dial. At 38mm and just 9.5mm thick, it disappears under a shirt cuff. It is the most wearable watch on this list, and the one that first made me understand why my grandfather only ever needed one.
4. The Chronograph: Seiko Prospex Speedtimer SSC813 (~$725)
Owning a chronograph changes how you think about time. The SSC813 is solar-powered with a tachymeter scale, built on Seiko’s Prospex platform — meaning it is also genuinely robust. At $725 it sits at the approachable end of the Speedtimer lineup and does everything a chronograph needs to do. If you have been on the fence about whether you would actually use a stopwatch complication, start here before spending Speedmaster money on the answer.
5. The G-Shock: Casio GA-2100 (~$99)
There should always be one watch in your collection that you are genuinely unconcerned about. The GA-2100 — the CasiOak — is that watch. Carbon Core Guard construction, 200m water resistance, 31 time zones, a 1/100-second stopwatch, five daily alarms, all in a case measuring 48.5 × 45.4 × 11.8mm and weighing 51 grams, with a battery life of approximately three years. At $99 it is the most capable watch on this list per dollar spent. Wear it on the trip where everything goes wrong.
6. The GMT: Seiko 5 Sports GMT SSK001 (~$495)
The GMT makes the most sense the moment you actually need it. The SSK001 runs the Cal. 4R34 — automatic, 24 jewels, 21,600vph, 41-hour power reserve — with a dedicated red GMT hand and a bi-colour 24-hour rotating bezel that separates day from night at a glance. The case is 42.5mm wide, 13.6mm thick, and water-resistant to 100m. At $495 from Seiko’s official range, it is the smartest practical addition to an essential watch collection.
7. The Daily Beater: Timex Marlin Automatic (~$249)
The daily beater is the watch you reach for without thinking. It should cost little enough that a scratch does not sting, and look good enough that you are not embarrassed wearing it somewhere decent. The Timex Marlin Automatic delivers exactly that — Miyota 8215 movement, 21 jewels, 21,600vph, 38-hour power reserve, in a 40mm case on a leather strap that improves with age. It is the most approachable watch on this list and, for many people, the one that starts everything.
The Essential Watch Collection: Why These 7 Watches Every Man Should Own Make Sense
Seven categories. Seven different relationships with timekeeping. The must-have watches in a well-rounded collection are not about status — they are about making sure that whatever the situation, you reach for the right one.
My grandfather owned one watch his whole life and never felt he was missing anything. I have spent ten years trying to prove him wrong. The score is still undecided.
