Seiko Orange Monster Dive Watch

Realy just wanted to let you know Sams club has the for 106, thats a damn good price.

Anyone know whats the diff in the crown being at 3 o'clock vs. 4 o'clock?
 
I think Seiko does the crown at 4 because it is less likely to dig into your wrist when you wear it.

Plus or minus what? If it loses 5 minutes per week plus or minus 30 seconds that's excellent accuracy. If it's five minutes per week plus or minus ten minutes that's not so good. Whatever the accuracy, your watch is in need of adjustment....
 
The Seiko OM/BM are great watches for the money, and the lume on them are pretty much what all others are judged by. Here is my BM on a zulu and a lume shot.

About 20 secs. a day fast is the way they come from Japan or Singapore or Hong Kong... Wear it for a year and have it calibrated by a jeweler and you might get it to within 5 secs.+/- a day. I've been wearing mine since January and it gets off about 2 mins. a week.

Nice looking watch. I have one..but its a lousy time piece. It loses about five minutes a week. I hear thats true with them all.
Once the caseback is off adjusting the movement is easy. I lose about 5 minutes a week, maybe, and I could care less. If I needed precise timekeeping I would buy a digital watch that syncs with the atomic clock.

BAsed on my love for my Black Monster I bought a SKX007 that I love, too, and I should have a "new" (to me... watch is probably from 1981) 6309-7040 with the cushion style case. I love the way they look in pictures, so I hope the real deal lives up to it!
 
I wear my Seiko Military more than any other watch I own, gains about 3 minutes a week, no big deal.

It reminds me of the orange Doxa (1500$) that Dirk Pitt was throughout the Dirk Pitt book series by Clive Cussler.

Over the course of 24 hours, my black monster seems to be dead nuts accurate...maybe a few seconds +/- a day. I wear it from 6am to midnight then take it off and place it flat, face up.

I love it.
 
It's a diving watch. Of course it runs fast. To finish your dive a minute early because your watch is fast and surface and find you still have a minute of air in your tank may be annoying. But the alternative is... well... not good at all.

If you have the tool to remove the caseback the adjustment is easily accessable but, from what I understand, very sensitive. Make almost imperceivable movements and repeat until it is better. On the 7SXX movements the adjustment is tedious even for jewelers or watchsmiths.
 
My experience with automatic watches (self-winding, in the old days) is that all of them tend to run a little fast. Thats been true from my first one, a brand called Clinton that was so proud of being waterproof they packaged their watches in a clear plastic tube filled with water, to the TAG that I wear now. I reset it once a week, no big deal.
 
Mechanical watches are generally regulated to run a tad fast. The reason for this is that there is nothing that can happen to the watch to cause it to run faster than its regulated to. But, there are many things that can cause the escapement to "skip a beat." A movement of your hand can, for example, impart to the escapement, inertia that causes it to "skip a beat." This will result, depending on the movement, in the loss of anywhere from 1/10th to 1/4 of a second. Watchmakers generally regulate their movements to run a bit fast to allow for some of this.

This is why when a mechanical watch is left unworn (perhaps manually wound) or when put on a mechanical watch winder which uses gentle movements, mechanical watches tend to run fast because they're not experiencing those movements and incidents that sometimes cause them to miss a beat and slow down.

You don't keep track of your air with a watch.

Suunto? ;)

The Seiko Monsters are a respected "standard" over in the Dive Watch forum. Have it adjsted after you've worn it for a month or so - then have it modded by Jack over at IWW! :D You'll love it even more! (I have one bead-blasted and one done in Mil-Spec black Teflon)

Ditto. I don't think I've adjusted my black monster since daylight's savings and it's right on time.

I have a Bill Yao 007 model that gains 22 seconds a day, however.
