Building a traditional darkroom involves plenty of decisions, but timing your prints shouldn't be one of them. For vintage photography shooters who develop film and expose enlarger paper, a reliable clock is the quiet backbone of the process. The GraLab Model 300 is a mechanical darkroom timer that has been part of that workflow for years, and this particular unit is listed at USD 49.99. The question is whether it fits the way you work.
Quick Verdict
If you want a straightforward, mechanical timer for enlarger and safelight control, the GraLab Model 300 is a legitimate candidate. It is described as tested and working, comes from the Dimco Gray Co. era of American manufacturing, and is built around a 60-minute mechanical dial rather than a digital display. At $49.99, it delivers the core functions you need for traditional printing without unnecessary complexity.
Who It Suits
This timer suits anyone committed to a film-based darkroom workflow - especially those who appreciate tactile analog controls. Because it has separate outlets for an enlarger and a safelight, you can switch both from the same unit, which simplifies the rhythm of exposing and then handling paper under safelight conditions. It also fits collectors of vintage photographic equipment who want a recognizable piece of darkroom history.
What Stands Out from the Listed Details
The GraLab Model 300 is a mechanical 60-minute timer with a 120V AC power requirement and a 750-watt maximum resistive load. That means it's designed for standard enlarger and safelight setups without overcomplicating your wiring. The separate outlets are a practical feature: one for the enlarger, one for the safelight, both controlled from the same timer. The description also notes it was made in Dayton, Ohio, USA, which adds a point of interest for anyone drawn to American-made darkroom gear.
Another notable detail is the unit's condition. The listing describes normal cosmetic wear from age and use, including light scratches, paint wear, and minor finish loss. For a vintage mechanical timer, that type of wear is common and does not necessarily affect function. The unit is described as having been tested and working, which is reassuring for a piece of equipment that depends on mechanical reliability.
GraLab Model 300 Darkroom Timer Vintage Photography Film Developing Works
This version of the GraLab Model 300 comes with the features that matter most for enlarging: a 60-minute mechanical timer, separate enlarger and safelight outlets, and a 750-watt resistive load rating. The listed price is USD 49.99, and the item is described as tested and working.
What makes it worth considering is the combination of tested function and the mechanical simplicity that many film workers prefer. There is no menu system, no battery, and no digital display to fail - just a dial that does its job. The main limitation to keep in mind is the cosmetic wear: light scratches, paint wear, and minor finish loss are visible in the photos. If you need a pristine showpiece, this may not be it. If you need a functional darkroom timer that has lived a useful life, this unit fits the vintage photography workflow well.
Meaningful Trade-Offs
The biggest trade-off is mechanical versus digital control. A 60-minute mechanical timer gives you that tangible, hands-on feel, but it lacks the fine-grained precision of a digital timer with increments in fractions of a second. For basic exposure times in printing, the mechanical dial is generally adequate, but if your process depends on repeatable sub-second timing, you might find the mechanical approach limiting.
The 750-watt maximum resistive load is worth noting. Most standard enlargers and safelights fall well within that range, but it's still a specification to respect when planning your setup. It's not a limitation for typical use, just a boundary to keep in mind if you ever consider running additional equipment from the same timer.
Bottom Line
For $49.99, the GraLab Model 300 offers a tested, working mechanical timer with the two-outlet convenience that makes darkroom printing smoother. It's not a digital precision instrument, and it shows its age cosmetically. But for anyone building a traditional film darkroom or adding a piece of vintage photographic gear to the shelf, this timer delivers the essential function without overcomplicating the process. If you're comfortable with a bit of patina and value the mechanical approach, it's a solid choice.
