Armitron lists the Knox 40 mm Navy/Silver/Brown (SKU 20-5626NVSVBN) at $140 and says its dial has 16 genuine diamonds. That makes it an affordable-looking entry point by the listed price, but not a verified market-wide bargain: the featured version is marked out of stock, and the diamond claim is the manufacturer’s, with no independent gemological verification established in the sources reviewed.
What “genuine diamonds” means for the Knox
Armitron describes the Knox dial as having “16 genuine diamonds” and calls them “genuine diamond indices” on its official product page. This is the manufacturer’s claim. The page does not provide diamond weight, grading, origin, or independent authentication, so the claim should not be read as evidence of a particular diamond quality or resale value.
Price and availability
Armitron lists the Navy/Silver/Brown SKU 20-5626NVSVBN for $140, but the product page marks it out of stock. The official Knox collection shows other variants listed at $140 or $150, also marked sold out in the retrieved listings. These are listed prices, not proof of completed sales or present availability from another retailer. Accordingly, “affordable” is a relative description of the listed price—not a demonstrated comparison with the wider watch market.

What to consider before buying
Check the exact version and live offer
Because the featured color is marked out of stock on Armitron’s page, check that any retailer listing identifies SKU 20-5626NVSVBN and matches the Navy/Silver/Brown version. Confirm the live price and stock status with that seller; the manufacturer’s listed price does not establish another retailer’s current offer.
Do not infer diamond value from the count
The stated count of 16 does not reveal carat weight, grade, or independent verification. If documented diamond characteristics are important to your purchase, the information on Armitron’s page is not enough to establish them.
