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.

My Indiglo is my "got to "watch , so I hope my solar powered will be as popular……. . p. s."

Q&A
Is the 15% discount stackable with sunny25 ?
Hi Jim! Thanks for reaching out. The 15% discount cannot be combined with any other discounts or rebate codes, including SUNNY25. Each promotion is applied individually at checkout, so they are not stackable.
I signed up to get the 15% off, and I have not yet received an email. Please send right away, or give me a code so I can make my order.
Hi Arlene! I'm so sorry to hear you're having trouble with the promotion code! That's definitely not the experience we want you to have. I appreciate you bringing this to our attention. To get the quickest help, please reach out to our customer service team for further assistance. We're available by phone (1.888.727.2931), email (timex.com/pages/contact), or live chat (lower right corner of timex.com) Monday - Friday, 9:00 AM - 7:00 PM EST. They'll be happy to assist you.
Is the Anti-reflective coating on the internal crystal? Or applied externally?
Hi Mark! Thank you for your question about the Expedition® Field Post Solar 41mm Eco-Conscious Fabric Strap Watch. The anti-reflective coating is applied underneath the crystal rather than on the outside surface. This helps protect the coating from scratches and wear while still improving visibility and reducing glare when viewing the dial. We appreciate your interest in this model and hope this information helps!
my watch does not last 8 hrs. can i change the battery?
Hello Gary! Thank you so much for reaching out, and we’re happy to help clarify this for you. The Expedition® Field Post Solar watch is powered by light, so it does not use a traditional replaceable battery. If it is not lasting as expected, it may need extended exposure to strong natural or artificial light to fully recharge. We recommend placing it in direct sunlight for several hours and, if the issue continues, contacting our customer service team for further assistance.
I would like to buy just the fabric strap (black) for Expedition Field Post Solar. What is the product # for the strap Thanks
Hi Scott! All our watches are sold as shown in the product images, so we don’t sell the bracelets separately. Unfortunately, we also don't have replacement fabric straps in stock.
