Seiko Prospex Solar Diver
Choose the Seiko Prospex Solar Diver if you dive, swim often, or want a solar watch that runs for months without winding and survives 200 m of water.
- 200 m water resistance suits diving and swimming
- Solar charge holds 6 months, so no winding or battery swaps
- Hardlex crystal resists scratches better than mineral
- Analog-digital display adds a second time zone and alarms
- $500.00 at Amazon is over three times the Fossil's price
- 47.8 mm case and 50.5 mm length wear very large on smaller wrists

Questions and answers
- Which is better for swimming and diving?
- The Seiko. It is rated to 200 m and built as a diver; the Fossil is rated to 50 m, which covers splashes only.
- Is the Fossil Townsman worth the savings?
- If you want an automatic dress watch and won't get it wet, yes. At $137.56 at Amazon it costs $362.44 less than the Seiko's $500.00 at Amazon.
- Which lasts longer between services?
- The Seiko's solar movement has no mainspring or rotor to wear, and its 6-month charge means it keeps running. The Fossil's automatic needs regular wear or winding and a service interval typical of mechanical watches.
- Which is easier to read?
- The Seiko. The Fossil's skeleton dial, dark Roman numerals and tinted glass make the time hard to read, especially in dim light, according to buyers.
- Which suits a small wrist?
- The Fossil. Its 44 mm case is smaller than the Seiko's 47.8 mm diameter and 50.5 mm length, which wears large.
- Can I swap straps on both?
- Yes. Both take 22 mm straps; the Fossil is sold as interchangeable-compatible, and the Seiko's silicone strap can be changed at its 22 mm lugs.
