Since picking up my silver and black Citizen Promaster Sky models, I just don't have time for a lot of my other watches, so my Benarus Megalodon and Benarus Moray Dart 44mm are now on the eBay auction block.
Essential Seiko reading: Jack Forster waxes poetic on the Seiko 5 and the 7S26 movement, which he pronounces "as brutally efficient and stripped to essentials as a Kalashnikov, and like a Kalashnikov, it is designed to work, as well as possible, with as few parts as possible, as efficiently as possible."
I have a theory: Everyone has a different limit. And the limit is defined as thus: There's a point where you can't experience the splendor of your most favorite watches because they've been diluted by others in your collection. Get rid of some of your watches and, voila, your grails, once dull under the weight of too many watches, now shine with the luster and resplendence they deserve.
I've been smitten by the Seiko SBDB009 but the spring drive technology requires special servicing.
Same with the less expensive Seiko SBBN013, Darth Tuna, which cannot be opened from the case for the quartz battery change but needs a delicate removal of shroud, sapphire crystal, and other parts. Specialized dealers in Japan usually do it.
Once a watch starts to create anxieties, it's no longer a pleasure to own.
