Here's an Aragon Divemaster 45mm with open heart and mother-of-pearl dial. I've had it less than two months, long enough to confirm that a 45mm watch this thick is just too big for my puny 6 1/2" wrist. So off it goes.
Specs include: Seiko NH38A 24-jewel movement. Diameter 45mm, thickness 17mm. Screw-down crown. Nice heavy stainless steel bracelet (extra links included) with a "Fliplock Safety Push Button Deployant Clasp." Rated for 200 meters. Display back, which I forgot to take a picture of.
The mother-of-pearl is very subtle; at first I thought Aragon had mistakenly sent me one with a black dial. In sunlight there's a nice color gradation, but nothing that screams "inside of an oyster." There are minor scratches (Are they swirlies? What's the definition of a swirlie?) on the case and bracelet. As far as I can tell, the mineral crystal and bezel are free of imperfections. The box is cool and heavy and very blue.
These list for $219, but everyone knows Aragon is always running sales. This one will cost you $115, including U.S. shipping and PayPal fee. I'll ship to other countries, but I'll have to charge extra for shipping. The watch plus box is a pound and a half, so overseas postage would be considerable. Feel free to make a (reasonable) offer or suggest a trade; I'll consider just about anything mechanical (hand-wind or automatic).
Please PM if interested. Thanks.
