I have a Davosa Ternos which, in my opinion, is a great homage to you know what. The one drawback I had was the lume–not so much as the brightness but the color. The original lume was C3 which, once charged by the sun or light, gave the hands and markers a greenish-yellow color. Nothing out of the ordinary there. However, during the day the white markers and hands would keep this color which for me was not that attractive. I always enjoyed the white against the black dial rather than a…

I have noticed in jewelry stores that used watches, even with brushed lugs, have a nice sparkle--that is, nice shine and gleam to them. i saw a Blusey which is a 5 digit model with a nice sparkle to it. How do they achieve the sparkle? Thanks

I have a watch with a crystal which is, I assume, boxed dome--it sticks up above the bezel by about 1.3mm and curves upwards so that the apex is about 2.25mm above the bezel. I googled the brand, a Steelflier SF733 (homage to Newman's Daytona), a...

I have a watch with a crystal which is, I assume, boxed dome–it sticks up above the bezel by about 1.3mm and curves upwards so that the apex is about 2.25mm above the bezel. I googled the brand, a Steelflier SF733 (homage to Newman's Daytona), and A.I. gave the measurements as 30.50mm in diameter and 3.8mm thick. I am wanting to install a flat crystal as I do not like the distortion the crystal on the watch gives. I measured the crystal with a digital caliper and 30.50 seems to be…

I have watched several of Marshall Sutcliffe's videos (Wristwatch Revival) and find them fascinating and informative. What I like is how excited he gets when doing his work. Interestingly, I find his videos strangely relaxing. Is Marshall the WIS version of Bob Ross?

OK, nothing controversial here–no grandpa's watch, homages, etc. I thought I would just post about Wristwatch Revival and how it is a really educational and fun to watch.

I am going to swap out a clasp on a metal band and will need to remove the friction pin (has a tube and two friction fitting pins for either end. This is the pin that inserts in the clasp holding the link to the clasp as well as holding the safety flipper on. The clasp is a tri-fold. I was thinking I could try and get a knife blade under the head and pry up. Is this possible with a friction pin or does one need to cut it and then use a new friction pin? They are cheap enough at…

This past Saturday my bezel insert decided to pop off the bezel. It popped off unbeknownst to me and for the past two days I have been on my hands and kneels looking for it–at home and in my car. It is amazing how many dust bunnies I found and was able to put to rest. Today I found it laying on the breakroom table at work. Someone had the wherewithal to not throw it away.

Now to my question. What is the best way to re-attach the insert? Superglue? Waterproof Contact Cement? Those…

This watch showed up in my e-mail from Marc at Islander Watches. I am not a golfer but was intrigued and noticed the insertion of 109 yards instead of 100 meters. I was impressed with that addition, as well as the math. Nice job. The dial displaying a golf ball is another nice touch.

As to my the title–well, I was on the fence with this one. Above par can mean above average but in golf one wants to be below par. In this case, the watch is definitely better than average and the score…

I have noticed a substantial number of chronographs, manual and automatic, which have a 30 minute timing subdial. This goes back to pre-WWII days up to the present. I understand the mechanics of the subdial but am puzzled why the subdial would only measure 30 minutes and not 60 minutes. Don't get me started on why Tudor is 45 minutes. It seems logical that one hour would be a better choice. This question is for the historians out there. Is there a reason why the timing subdial for many...

A couple of weeks ago I sent an e-mail to Seiko's Service Department with questions about the VK/8T movements (chronograph meca-quartz). So far, all I hear are crickets. My e-mail said nothing about their crappy bands on the watches in the price range of $150-$300 (if the Ali-watches costing well less than $100 can provide reasonably good bands Seiko should be able to do so ) or their hit or miss QA/QI (misaligned bezels, poor placement of springbar holes, etc.).
