Cazalea's exploration of watch caseback shapes, sparked by his Seiko Astron, delves into an often-overlooked aspect of watch comfort and design. This article examines the ergonomic implications of concave, convex, and flat casebacks, inviting collectors to consider how these subtle differences impact wearability. Cazalea's initial post challenges the community to identify 'comfortable heroes' and 'hard-to-wear villains' based on caseback geometry.

Wearing my Seiko Astron today, I began to wonder about caseback shapes.

How many are concave:



Curved to confirm with the arm’s circumference.



Versus those that are convex, or protruding into the space between your arm’s bones (or into your arm itself).



As in the Bell & Ross Space4?



Can anyone nominate a comfortable hero, or a hard-to-wear villain?

Of course watches with transparent caseback are generally flat on the back, but perhaps not in every case(back). Ha ha.

Cheers,

Cazalea

One key aspect that is relevant when I pick up a watch is how it catches with cuffs or anything it could encounter while wearing it (pieces of furniture but also people's arms for example). For example, I find the Breitling Aerospace very catchy, which is a bit annoying. My JLC MUT34 is extremely comfortable, I guess the curved lugs are key contributors to this comfort. Best, E. PS: tell us more about the Astron!!

...which helps a lot with their wearability

The first Astron-labeled watch was Seiko's first quartz model. Here's a photo from the Seiko museum - you can see the shape. Mine is one of the Anniversary editions - I bought it on a whim at Feldmar's in Los Angeles while on my way to a Feb 29th GTG in Santa Monica. One of 200, it had come out a year earlier and somehow got lost in their inventory OR in 2012 no one wanted to touch a quartz watch with list price $4000. They showed it to me, offered about 30% discount and I bought it on the spot.
