Live Price Comparison for "smart watch"

Seiko 5 ($350-450) — automatic, durable, decades of resale history. Hamilton Khaki Field ($550) — military-style classic. Tissot PRX ($450-700) — modern integrated bracelet. Skip $100-200 'mechanical' watches from no-name brands — quality control is hit-or-miss. Pre-owned vintage from 1970s-1980s is also a great entry point via Crown & Caliber or Hodinkee Shop.

Quartz (battery-powered): more accurate (within 15 seconds/month vs 5-15 seconds/day for mechanical), cheaper, lower maintenance. Best for daily wear. Mechanical (Swiss/Japanese automatic): no battery, lasts generations with service, has heritage and craftsmanship appeal. Most watch enthusiasts own both — quartz for daily, mechanical for special occasions.

Every 5-7 years for full overhaul (cleaning, oil, regulation) — $200-800 depending on brand and complexity. Swiss/Japanese mechanical watches (Seiko, Hamilton, Tissot) cost less to service than complicated calibers (Rolex, Omega — $500-2,000). Skipping service eventually causes drying oils to wear gears irreversibly.

Yes for buyers who value: heritage, resale (most Rolex models hold or appreciate), durability (multi-generational), and brand recognition. No for buyers seeking pure timekeeping — a $500 Seiko keeps better time. The 'investment' angle: certain Rolex models (Submariner, Daytona, GMT Master II) have appreciated 100-300% over the past decade due to scarcity.

Under $500: Seiko 5 sports, Hamilton Khaki Mechanical, Citizen Promaster. $500-1,500: Hamilton Khaki Field, Longines HydroConquest, Oris Aquis, Tissot PRX. $1,500-5,000: Tudor Black Bay, Grand Seiko entry, Omega Aqua Terra. The Grand Seiko Spring Drive is the cult favorite at $5K — incredible craftsmanship at half Swiss-luxury prices.

Wrist circumference determines case size. Under 6" wrist: 36-38mm case. 6-7" wrist: 38-42mm. Over 7" wrist: 42-46mm. Most modern watches are 40-44mm. Vintage and dress watches trend smaller (36-38mm) — back in style with the slim-fit clothing movement. Try multiple sizes at a jeweler before buying online.
