Watches using the 218 Series of movements are much more conventional than the 214-based ones: they have a stem and crown although this is usually at the 4 oclock position; they can take a modern 1.5 volt Silver Oxide battery with only minor re-phasing adjustment.

Here are some of the more well-known calibres in the 218 Series:

• 218D: Early 218 with date
• 2180: No day or date calendar mechanism
• 2181: Date calendar mechanism
• 2182: Day and date calendar mechanism
• 2183: No day or date calendar mechanism and no second hand. Usually found in thin dress watches.
• 2185: GMT watches with second crown at 2 oclock for second time zone

In addition, Bulova experimented with various hacking mechanism in the 218 Series; the later types are indicated by a letter after the four digit calibre number. For example:

• 2182: Hacking via a post that lifts the pawl off the index wheel. Battery remains connected.
• 2182F: Introduction of electrical contacts that means the ground plate of the component coil is isolated from earth once the crown is pulled out. Adjustable collect that touch tuning fork when crown is pulled out. Battery is disconnected when the crown is out.
• 2182G: A more complex electrical contact system that is now an integral part of the component coil; to support this, a new hole has been made in the main movement plate and the stem has 3 setting positions: normal (in), first which hacks the mechanism but does not disconnect the battery and second which disconnects the battery. Due to these changes, many parts from the 2182G calibre are no longer interchangeable with the 2182 or 2182F calibres.
