This is my first attempt at assembling a watch, so I'm posting this.。When I say assembly, I just bought parts from Lucius Atelier and put them together.。。 I tried matching it with brown parts to match the fall, but it arrived late from Lucius and by the time I assembled it, it was mid-winter 💦 All parts are from Lucius Atelier： Case: Explorer Watch Case – 36mm [ULTRA THIN EDITION] Movement: Seiko (TMI) NH38 Automatic Movement – Open Heart needle: The Great Fathom Hands Dial: The Bronze Medallion Diver Dial (No Date) Chapter ring: SKX013 Brushed Silver Chapter Ring Strap: All the Geckota tools I had that were missing were purchased from Mr. Manager.。It was difficult to place the needle horizontally, but other than that I think the work went smoothly.。 However, the retainer with model number 19500 was a little strange.。。Not only this watch, but all the watches I own cannot be installed stably, and the bezel gets in the way and seems to float up.。。I regretted that I should have gone with SEIKO S-212 as recommended by the store manager, but I ended up cutting it with a router and processing it to fit most watches.。
