For a useful comparison, start with specific models. Hamilton’s Khaki Field Expedition Auto H70315130 is a 41mm automatic with sapphire crystal, an 80-hour power reserve and 100m water resistance. Timex Expedition includes several types of watch; its Field Post Solar is a light-powered option offered in 36mm and 41mm sizes. Your best fit depends on the movement, size and price of the exact reference you want.
Which models are being compared?
This comparison uses the Hamilton Khaki Field Expedition Auto H70315130 and Timex’s Expedition Field Post Solar as concrete examples. They are not direct equivalents: one is an automatic Hamilton listed on an international storefront in Swiss francs, while the Timex examples are solar-powered watches listed by Timex US in dollars. The Expedition family also includes quartz, automatic, chronograph and other watches, so a different Timex reference may change the comparison substantially.

Hamilton identifies H70315130 as a current Khaki Field Expedition Auto. Timex’s collection page shows 36mm and 41mm Field Post Solar variants alongside other Expedition models. Check the precise reference and its local product page rather than assuming that a feature or price applies to an entire collection.

What does the movement mean in everyday use?
Choose the Hamilton if you want an automatic
The H70315130 runs on Hamilton’s H-10 automatic movement, which winds through wrist motion. Its stated 80-hour reserve can keep the watch running for roughly three days off the wrist, though actual operation depends on how fully it is wound and worn. The model also has a Nivachron balance spring. The manufacturer lists the movement and reserve; the available information does not provide an independent accuracy or durability comparison with Timex.
Choose the Field Post Solar if you prefer light-powered operation
The Field Post Solar uses light rather than a conventional battery change as its normal power source. Timex says its solar reserve lasts up to four months. Treat that as a Timex claim for its solar context, not a promise for every Expedition or a direct measure of service life. The Expedition collection also includes automatic and quartz choices, so identify the movement on the individual Timex reference before buying.

Which size is likely to fit better?
The Hamilton example is 41mm across and 11.5mm thick, with a 20mm lug width. Timex’s Field Post Solar appears in 36mm and 41mm options. A 36mm case will generally present less width on the wrist than a 41mm case, but diameter alone does not determine comfort: thickness, lug-to-lug length, strap, and wrist shape matter too. The listed Timex pages do not establish those full dimensions for the solar variants, so compare the exact model’s measurements or try it on if fit is decisive.
What do the construction and water-resistance claims establish?
Hamilton specifies sapphire crystal, a stainless-steel case, a screw-down crown and 10 bar (100m) water resistance for H70315130. Timex describes the Field Post line as using anti-reflective sapphire crystal, luminous hands and hour markers, and a screw-down crown and caseback that provide 100m water resistance. These are manufacturer specifications for the cited Hamilton reference and Timex sub-line, not guarantees about every watch in either collection.

A 100m rating is a stated water-resistance specification, not a substitute for checking the manufacturer’s care instructions or the condition of a particular watch. For either brand, verify the rating on the exact reference you are considering, especially if your intended use involves water.

How should you decide?
- Favor the Hamilton example if you specifically want an automatic movement, an 80-hour stated reserve, a 41mm stainless-steel case and the listed sapphire and 100m specifications, and its regional price fits your budget.
- Favor the Field Post Solar if light-powered operation appeals to you or you want a 36mm option while retaining Timex’s stated sapphire and 100m Field Post features.
- Look beyond these examples if your priority is an Expedition quartz or automatic watch, another case size, or a lower price: Timex’s collection contains multiple models at different listed prices, and they do not share one specification set.
- Before ordering, compare exact reference numbers, dimensions, movement, materials, water rating, local stock and current local price. The available price listings are not a same-market, same-date comparison.
