Hi orangedial! In my opinion, both of these pieces give very different feelings. For the Jumbo, the first visual impact is stronger. I guess it's because of its hard line, proportion & shap of the RO. However, it doesn't overwhelm your wrist at all! Thanks to the extra thin case of the jumbo. As for the aquanaut, the softer line gives somewhat a less impact of first impression but there is something about the aquanaut. It is a very subtle watch which gives poetic feelings. With the steel bracelet, it gives a more robust & solid feel & the proportion is also excellent. Not to mention the quality & craftsmanship, it is indeed second to none. I think the dial color is something worth mentioning as well. you really have to be in person to see the actual dial to appreciate especially looking at it under the sunlight. Based on history, the Jumbo is a more significant piece. Perhaps, the more appropriate comparison should be made between the Jumbo & the Nautilus. Anyway, both of these pieces are excellent dress watches & very versalite.in terms of wrist time, I guess it comes down to what outfit would fit better with which watch. Given the fact that we tend to go for bigger time pieces these days, these 2 pieces with only 39mm & 40mm still look pretty good among the bigger models nowadays. I know they will continue to be my favorite for many years to come. Here is few more shots from my daily album. Enjoy!
