One of Timex’s better cheap digital watches. If impact resistance is primary, pay a few dollars more for a G-Shock DW5600. Timex displays are bigger and easier to read. Lug width 22mm so replace that ugly strap. You can replace the button battery yourself with a tiny screwdriver and a flexible probe to push the battery out of its casing (I recommend the plastic toothpick on a Swiss Army Knife). Do not try to replace the gasket, just lubricate it with a drop of Trident silicone grease which you can buy from any dive shop for a few dollars. Not a fan of white on black displays so I’m dithering over buying one. Good price for what it is.
