Where’s the rest of them?! 

 Honestly I wondered that too at first.  For the people who don’t know, these guys originally had like five or six variants.  Each were progressively stronger than the last up until the adamantine version, of which only one existed and it basically acted as the central brain for the race (reminiscent of the borg). 

Basically this thing can communicate in eldritch morse code, right?

Wow this is more powerful then I expected. (I expected a 1/2 or maybe 1 challenge level.)

 Absolutely, and they likely use this to quickly communicate across the length of their fleets without needing to be next to each other

Only CR 2?

Granted the bite and the saw don't deal much damage but damn these things are built like tanks.

I kind of hope we eventully get some varients 

This is some Final Fantasy X fight right here.

Love it!

A spell attack is the roll you make to hit with a spell!
As such Clockwork horror cannot use Lightning Jolt because it is NOT a spell.

Spell attacks don't mean you're casting a spell, its just a differentiation between a weapon attack or otherwise. An example I'd use is the three Radiant Soul monk features; the radiant sun bolt is a spell attack but not a spell, very similar to the lightning jolt attack on these little fellas. The 6th level Searing Arc Strike specifies you cast Burning Hands as a bonus action, therefore you can counterspell that. However, Searing Sun Burst just uses an action to magically create the explosive orb, therefore you can't counterspell as it doesn't meet the counterspell trigger. However, magic resistance would give you advantage on the saves for Arc Strike and Sun Burst as they are a spell and other magical effect respectively.

I stand corrected:

Is a spell attack a spell?

No. The game has two types of attacks—weapon attacks and spell attacks—so a spell attack is a type of attack, not a type of spell. Sometimes a spell attack is part of a spell, as in the fire bolt spell, but other times a spell attack occurs outside a spell, as in the specter’s Life Drain attack in the Monster Manual.

I love the art

I am also wondering where the rest of these guys are.

strange, its bite attack is strength, its sawblades appear to be dex, but it's lightning jolt makes me think it is constitution based.

 Its Wisdom based. Look at the modifiers and saveing throws, the math checks out. Its odd that a machine is a wisdom caster, but that's the best choice for it lol

That art just makes me think of a certain set of lyrics.

 a spell attack is the roll you make to hit with a spell or spell like ability. 

Fun trivia fact: an unarmed strike (without a weapon) counts as a weapon attack.

It’s so futuristic compared to most other constructs

 Their Lightning Jolt is STR or DEX based, nor CON based. Also, there is no indication that their Bite is strength based or it’s saws are DEX based, since their strength and DEX are equal.

ALL YOUR BASE ARE BELONG TO US.

 I agree

Maybe it's to represent higher levels of perception and awareness?
