You may be right, but due to past experiences, I doubt that an EL or Andy or Joshua without mods are so solid and accurate than a MBW. At least, my modern MBW 16610 is waterproof (swimminpool diving, yes) and accurate to -15 secs/month. To ensure that accuracy and waterproofing you have to pay an extra of 125 USD to Joshua + shiping, and you are paying near those 500$ (I paid 360USD for my MBW). And no mention about rehaut.
