I think it would be fun to make a thread focusing on selective groupings from individual brands, emphasizing quality and variety instead of quantity. Feel free to interpret the three-watch collection concept creatively.

I'll start with a 1960s Seiko trio: dress, dive, and chronograph.
[1964 Grand Seiko 43999, 1967 6217-8001 (aka 62MAS, first diver), and 1964 45899 Olympic monopusher, first chrono]

 

In the same order as Dan:

 

I’m interpreting as 3 generations of:

 

Oh- forgot one

 

Hamilton

 

I'm liking these generational collections. Good thought.

 

Good idea, Dan!

An early, small Art Deco with a rare case variation, followed by a large cal. 852 with an uncommon orange second hand, and, to punctuate variety, a combination alarm clock, thermometer and barometer.

 

A clock?!! Should've known Tony would take it to the next level.

 

Three U.S.Army Veterans.
From WWI:

From WWII:




From my service in Korea, 1972:

 

Wow! The US Army issued Soccer Timers to troops?



Nice group Jimbo.

 

A trio of vintage complications (L to R) circa 1945, 1943, and 1953:


A trio from the thirties, circa 1936:

 

Hamilton cal. 982: the American Patek. (Left to right) Custer, Brock, Gilman.

 

Demonstrating Eterna's diversity, here is my trio with no stylistic overlap with @Tony C.'s.

1940s military, 1950s chronograph, 1960s diver.

 

3 generations of kontikis

 

Not all mine anymore. And four in stead of 3. But I had a thing with the 120...

 

So basically a picture of three watches (Edit: missed the single branded so Swiss brand will do )

So three Chronograph’s


3 stopwatches


My three travel watches
Sea - Land - Sky


Underrated Trio

 

5227r, 6119r, 5167a



Sidebar: the 6119 is the most accurate hand wound I’ve ever owned, ~0.25s/d.

 

No, no, no ... we were doing so well until you rebels showed up.
@Shabbaz: three-watch collection. @STANDY: single-brand.

(nice watches though)

 

Swiss branded

 

I'm sorry. You're totally right. What was I thinking!?!
