While large hands have long been reputed to portend large manhood, large wrists have long gone unheralded, mostly because chicks don't care how big your bulbospongiosus muscle is. Proving large wrists can at least satisfy a desire for slick accessories: Greg Stevens Design.
From a dude in Utah who had to start making his own watch straps due to being “blessed” with enormous hand/arm connectors, GSD’s a lineup of (mostly) leather custom goods constructed using “Old World techniques” while looking cool enough to be worn by those not in their Middle Ages. His Pilot-style, Swiss movement GSD-1 watch can be had with either a white or black glow-in-the-dark face, a PVD or brushed steel case, and your choice of two customizable straps from his 20+ strong stock, which ranges from broad, edge-stitched Horween jobs, to pieces cut from vintage military ammo pouches that “smell like history”, though hopefully not the part that predates septic systems. Other customizable accessories include dual-pocketed wallets/biz card cases, belts and buckles, and classed-up key fobs that resemble the shorter half of a watch strap complete w/ a clasp, so you might want to pick up a watch as well, as "I lost my keys" will no longer be a valid excuse for showing up late.
For serious enthusiasts, he's also got a variety of upkeep products, from leather conditioner, to polishing cloths, to a strap storage case made from antique ammo cans, which, just like dudes with large hands, are kind of useless if they're filled with blanks.
