We're not sure on pricing, seems like the Sport will be the least expensive. But which one to get? Sport has lightweight aluminum, but the ion glass. The regular has sapphire glass, but stainless steel. Sapphire is better than ion glass, but isn't aluminum better than stainless steel in a watch? Lighter weight, just as strong, or strong enough for a watch? Airplanes use aluminum. I doubt if the solid gold is only $1k, but if it is, then maybe it'll be worth it for the jewelry box and for the gold.
