The band for this watch can be adjusted to fit comfortably between the following wrist circumferences.
150 - 205mm (5.9 - 8.1in)
Wrap a garment measuring tape snuggly around your wrist just below the wrist bone. Alternatively use a piece of string and then measure the string length with a ruler. The average wrist size for men is 6.5-7.5", and for women is 5.5-6.5".
How to choose the right case size
Case diameter determines the watch size: it’s the width of the watch case, excluding the crown. Small wrists (<6") suit 28–36mm, average (6–7") fit 36–42mm, and larger wrists (7"+) can wear 42mm+. Smaller cases can feel refined or vintage-inspired, while larger ones make a bold, modern statement.

Sapphire Crystal
Nearly impossible to scratch, the sapphire crystal lens is as hard and clear as a gemstone. There are only a few materials known to the world that can scratch it.
Sapphire Crystal
Scratch-resistant
Sapphire is the hardest crystal available. Given its hardness it is near impossible to scratch, however, it can be prone to shattering if subjected to a heavy impact. Its scratch resistance is very desirable and as such there is a higher cost to sapphire versus other crystals.

The hands and hour markers
"The hands and hour markers aren't easily visible at night. The stainless steel watch feels light on the wrist. The silicone strap is very comfortable. The 41mm variant has an attractive design. Timex processed and sent my order promptly."

"So far, xcellent piece. I own an Omega Seamaster and an Oris Big Crown Pro Pilot. The little Timex is a GREAT! addition. I’m actually a tradesman and super hard on watches so a “cheap” watch is an essential part of my day. The Expedition keeps great time, the second hand pops perfectly to the second marks and the feel and look is perfect. 10/10 at this price point!!"

Q&A
Does this watch say, "WATER RES. 100 METERS" at the bottom of the dial near the 6 o'clock mark like the other Field Post Solar models? The indices in the photo are shortened, but no text is showing. Is this a mistake?
Hi Jonathan! Thanks so much for your question. The Expedition Field Post Solar 41mm Silicone Strap Watch does include the “WATER RES. 100 METERS” text near the 6 o’clock position on the dial. If it is not clearly visible in the product image, that would likely be due to the photo angle or image presentation. Rest assured, the watch is rated for 100 meters water resistance.
Hi. Does the dial have raised hour markers? Thanks
Hello JR! Thank you for your question about the Expedition® Field Post Solar 41mm Silicone Strap Watch. Yes, the dial features raised applied Arabic numerals, which help improve readability and add depth to the overall design. This detail gives the watch a more dimensional and classic field watch appearance. If you need any additional information about the watch, we’d be happy to help.
Are the hands and numbers luminous? Is the watch readable in the dark?
Hi Charles! Yes, it is! The hands and markers on the Expedition® Field Post Solar 41mm Silicone Strap Watch are luminous, making it easy to check the time, even at night or in dimly lit environments.
What is the weight in grams of this watch?
Hello Jonathan! Thanks for your interest in the Expedition® Field Post Solar 41mm Silicone Strap Watch. The weight of this model is approximately 80 grams, making it a comfortable and durable choice for everyday wear and outdoor adventures. If you need help comparing it with other Expedition styles, we’d be happy to assist!
Can I get different strap colors like blue or black
Hi Rob! All our watches are sold as shown in the product images, so we do not offer customization, such as changing the band strap. However, you can purchase a separate replacement strap with the correct lug width if you’d prefer a different color.
