Arrived today! This watch features the world's first commercially available Swiss quartz movement (The Longines UltraQuartz was technically an earlier development but could not be mass produced). Derived from some elements of the Beta 1 and Beta 2 projects, The Beta 21 housed a massive quartz "bar" that vibrated at a low rate of 8192 Hz which a circuit turned into 256 Hz output to drive the micro-motor that Omega was in charge of originally producing for the CEH. What results from this motor…

Just got this watch for $100… One of Citizen's High-Grade Crystal Sevens (has the same amount of jewels as the automatic Chronomaster at 33 jewels!) Couldn't pass it up, and the 33 jewel versions are pretty darn rare. Case finishing has additional bevels added to it versus lower jeweled Crystal Sevens, and all jewels are functional unlike the Seikomatic Weekdater's day/date wheel jewels. This one has the full day printed above the vintage Citizen logo (I love the style of these vintage…

Just arrived today – a Citizen Eco Drive One. Measures ~3mm thick – feels like I'm not wearing a watch at all. The dial is really amazing – looks completely different depending upon how the lighting in the room is (from a flat & dull finish, to a highly textured finish, to then a sparkling finish). The bezel is Cermet (mixture of ceramic and metal) to provide the necessary hardness to keep the thin watch durable.

The 8826 movement itself is 85 parts, 1mm thick, solar powered (eco-drive)…

If you could purchase watches (at the original asking price for the time but adjusted to inflation today, and brand new with box, papers, and warranty) and were locked into only being able to purchase watches produced in a specific decade, which decade would you choose? Keeping in mind that older watches tended to be cheaper to originally purchase (but lack modern material science and innovation).

For myself, I'd look to the 1970s – there are some cool vibrant designs (think KS Vanac)…

Hi all,

I was wondering if Tudor still swaps out the movements for a watch when a watch is sent in to be serviced. If so, does this mean that you get another COSC certificate for the "new" movement that was put into the watch?

Thanks.

Well, it's been precisely 1 month since I've received the Tudor Prototype 1 / Commando. I figured I'd do a write up since I've given this watch some considerable wrist time. The verdict?

I'm still loving this watch. A sporty GADA watch, really - especially on the metal bracelet. No buyer's remorse! It's unique, comfortable, and I think someone with 7+ in. flat wrists could pull it off even with it's 55.6 mm L2L length. I've been wearing this piece consistently throughout the month...

Which logo do you like more?

I personally love the old rose logo - and if they brought back the "Big Rose" Prince in some format, that'd be pretty awesome (though very unlikely).

These both fall within my maximum comfort zones for large and small watches.

I’d love to see yours!
