Seiko Battery Hatch
I have a Seiko 4336-8019 with the battery hatch in a snapon case back. It appears at the last battery change that the hatch was forced on 180d from where the arrows indicate. Now I can turn it in a 90d range but at no point does it want to pop off. I think this is some kind of bayonet mount and not a screw in.So, I tried using a case knife like this, to try and remove the entire back but apparently I can't find the knack of it either on this 4336-8019, or with a 6F22-7009 moon phase watch with a very smooth case back. I think I see the slight indentations on both cases at 3 o'clock. Maybe because my case knife is a cheapie, the blade isn't "sharp" enough to fit in the spot. Any advice on how to use this tool or how to deal with the off-phase battery hatch would be appreciated.

Do you speak "reference number language"?
For example, when at a AD will you ask "May I try on the 16610, please" instead of just saying Submariner? Or another example, if you are having a conversation with face to face with someone will you say "the 2220.80 and 2531.80 are both 'Bond' watches"?I am trying to figure out if I am the only one that speaks "reference number language". I call it a language because sometimes when I am talking to my friends it seems like all we hear are numbers, no brand names. When on the forums, I usually use the reference number of the watch I am talking about. This way the reader is able to determine the precise model he/she is reading about. It also helps me become more acquainted with brands that I am fond of.Now when I visit a AD and ask to try on watches I use RNL and most times they need clarification on which model I am asking for. No problem with that, I am not bashing AD's and that not the purpose of this post. They were just the easiest example I could remember. So, does anyone else spea

Elephant or Grey Ti44
I have been thinking of purchasing the Elephant, but just noticed the Grey titanium piece. I have yet to try on the 44, but I have a 7.25 wrist so I should be able to pull it off. Any thoughts from you guys as to which is the nicer piece for a grey watch?

Always an adventure when wearing my Sub!
Happy Holidays, guys. Thought I would share some pictures of my Sub, my truck, and I romping around in some fresh snow. I have had my SubC for a little over a month now, and still loving every second. It's great to know I'll always have it when making my fondest memories. Happy Holidays!Sent from my SM-G920T using Tapatalk
